Why is unraid so slow. Dockers and VM are disabled.

Why is unraid so slow UNRAID slow on writing, WHY! (2) UNRAID slow on writing, WHY! (2) By grumpy July 21, 2023 in General Support. I then checked the array speed (see attached screenshot "array3. I launched the default preclear on a 3To WD Red HDD and it feels really slow, 120MB/s, the read verification took one evening and a night, it's in the first write pass. There are probably many ways to solve the problem. Quite how severely is difficult to determine - it depends on how much activity and how much the drive heads have to move each time to The array is a lot slower than you think for that type of work. Akito March 17 Hey there, I just set up my first unraid server (file storage for my small business), created users and shares and started testing it. If not, do so. When I try to route my arrs through it, the connection is so slow to index or add new shows/movies I couldn't stand it. My download speed is so slow I dealt with this recently prior to going on holiday. For security reasons, Mac OS X 10. I previously ran a Plex server on my home PC without any issues. There was an /etc/init. In SABnzbd's upper right corner, click on the wrench symbol ("Status and interface options"), then click on first tab Status, and there click on the Refresh Circled Arrow. So different networks. I'm in the process of moving my VMs around to re-format that cache pool back to btrfs. I was advised that my transfer rate was incredibly slow. When I transfer a file from Unraid to my PC (via SMB shares) I get 2MB down, and when I transfer a file from my PC to Unraid I get 40MB up. I'm running binhex's qbittorrent container with Mullvad VPN and wireguard. I'm having a strange issue with mover write speeds to the array, the mover is only moving data off the cache drive (4 ssd raid) at about 50 mb/s. I have just recently deployed Overseer in addition to Radarr and Sonarr to my UnRaid Server for Plex. I think you have a weak link somewhere that's slowing it down to 10/100. Usually around 1MB/s, now it's only around 100KB/s. I am running Unraid version 5. I'm running it on unraid so I just wrote a script that runs hourly & on startup to check the overseerr container IP and update the conf file. Personally I, don’t use ssd cache for copy, my ssd pool used only for docker and torrents, any data that copying to my unraid - will be copied to HDD array, except mentioned torrents downloading, but I'm asking this question because it took me ages to figure out why the networking in my base ubuntu container was so slow, up to 50 times slower than the host OS, which made any kind of apt-get installations take extremely long (45+ minutes in some cases). I have stable even without a cache enabled, unraid will use RAM as a dirty cache for small files, so I suspect the 100mb/s is your network speed (gigabit lan) loading the ram cache and the 5-10mb/s is your true HDD write speed which is lower than should be expected unless you have data consisting of many hundreds of thousands of very small files. A few people in the Reddit group. You have the cpu's for it and it won't slow down like unRAID. Definately give the VMs an SSD, you can just make a share for vms and set it to cache-prefer or cache only and it iwll work, or use the unassigned devices plugin to mount a disk outside of the array and put the vdisks on that. the stats from unraid clearly indicates a write speed of 31MB/s and the dashboard shows im not CPU bound. Unraid is really slow at writes and you pay the price for how much available storage you have vs ZFS or a hardware raid setup. 2 to 6. Since moving I am getting some really up and down read speeds. The Docker aer basically unreachable. r/unRAID My ISP pretty reliably delivers around 550 Mb/s, so I'm trying to troubleshoot. My question: is there an optimal placement of disks on ports?. Before i would transfer files locally and would be in the 110-120 MB/s range. I'm new to Unraid, and pretty new to Linux as well, being a long-time windows user. Lately it's been in the 60 MB/s range. Thanks in advance. Over Ethernet, the speed is between 90 - 120 MB/s which is fantastic. Even using PIKVm inside RDP is better that use only pikvm. All the drives are recognized and it's running ok so far, but I'm running a parity check and i'm getting 1/2 the speeds currently running at about 55 M If so I believe you'd benefit from downloading directly to the second drive. One key thing I'm looking for is to have a system that uses less power and unRAID seems like a good solution. When files move from my downloads on the NVMe as well to my storage array, the server grinds to a halt. Everything is checking out as a gigabit connection. 9. SATA SSDs speeds with HDD capacity. I have just migrated my drives to a new system that has a lot more power for running VM's. Wondering with all drives newly formatted, why I need to sit through a full parity sync. conf file, you have to refer to it by IP. This is happening with every download, so I don't think it's a problem with the server. I will move all data from my cache to the array to add two disks and switch to zfs. I was wrong. 6. I immediately saw normal performance, 165MB~185MB/sec!!! I'm assuming you use SABnzbd 3. I'm a Mac user and when I use Finder to browse folders & files on my unraid box, I always find it tediously slow to update and expand folders - sometimes files don't appear Hi, my qbittorent download speed slowed down to only around 10% of my internet dl speed. I downloaded iperf but that needs it running on both ends? And I have Windows 11 -> unRAID and Ubuntu 22. Try using Double Commander, it's another file-manager-docker setup. i have CA tur Swapping from a 4TB parity to 8TB when the parity sync begins it still only shows 4TB and the speed of the sync ranges from 10-35mb/s very new to Unraid and Nas setup in general please be easy on me if this is a stupid issue LOL Please see screen shots and diagnostics report . So Wi-Fi was the issue. Unraid is only using my onboard NIC and a I have a single bridge on it for VMs (vm0) the docker0 bridge and my Intel dual NIC is being passed through to pfsense. Still, terribly long waiting times, but it has at least significantly improved compared to how it was before. Reply to this topic; Start new topic; This morning I shut down the unRaid server and booted up into windows - and tried the same download and achieved speeds approaching saturation of the line (around 890Mbps). So I have a machine where the Windows VM is the "front end" of the machine and used to maintain, administer and access the Unraid UI. I found this link from Synology. And I tested the same connection with different devices and the speed is there, just not for unraid for some weird reason. Hoping that going back to OS6 would fix this, I down-graded. Why docker build is so slow. So this thread is a good start but if we could somehow gather all the SMB information from the entire forum and make it useable, that would be something special. Right, finally found a spare 10 minutes to test this. (The config basically adds extended attribute and macOS metadata support. Looking for some insight why my rebuild is so slow. Windows 10 issue maybe? Quote; I'm asking this question because it took me ages to figure out why the networking in my base ubuntu container was so slow, up to 50 times slower than the host OS, which made any kind of apt-get installations take extremely long (45+ minutes in some cases). The Processor view often shows all cores to be used by nearly 100%: But when i look into htop everything seems to be fine: I've ran Proxmox before on this server where i had no performance issues at all. Dockers and VM are disabled. After getting back into Unraid and verifying the network changes worked, I added my two parity disks and started the array. Why are downloads so slow? I recently got plex pass for the first time to take advantage of being able to download movies and tv from my server onto my iPad and iphone for offline playback. 30. Cache is NVMe and array are usual HDD's Transferring data from the NVMe over my network giv I have had unraid running for several years flawlessly. Details bel I am trying to back up some files via rsync to an external SSD drive via USB3 - just copying new files over the past few days. 3 on a Synology NAS. So still at a loss why the transfer speeds between the server and my PC are so slow on a wired connection. The pool has 2 raidz with 3x2tb WDRED each (they all CMR). Can someone help please. Anyway, I did check to see if I could I tried to measure the overhead of LUKS/dm-crypt encryption on a XFS filesystem with default settings. They faded quickly so I only briefly saw the messages and that's when I noticed the empty drives, as all but 2 of my drives were sitting at This was so bad I really couldn't use Unraid (I have a Urbackup file I NEED to download to restore some data and it is so slow it continuously times-out and the transfer fails). Plex incredibly slow since moving to unRAID . 10mb/s is what I would expect of a network connection working at 10/100 not gigabit speeds. Help I just added a 2nd parity drive with 3 additional data drives and the parity rebuild/sync speed is hovering at 20-30MB/s and occasionally going up at 50MB/s and mostly dropping to below 20MB/s. BlackMagic Disk Speed on a Mac reports 110MB/s to a empty share, which is very reasonable (on Gigabit connection). At first the WebGUI was running flawlessly but now it can take up to a minute to load the page contents fully. I don't understand why MostFree wouldn't be the default. I am running ZFS on UNRAID with a pool created in a past trueNAS instance. After a ton of Google-fu I was able Although I think my lag is caused by the re-formatting of my cache pool from btrfs to zfs. The navigatio In Mac and Windows there are some volumes performance issues that we should consider. Hadn't really thought anything of it until I found another thread stating that their speed was slow at 80mb/s (?!?). Reply reply Jpeg6 Hi, I'm looking for some advice please. I've run through the performance tips and I have a few questions about some of the variables which might explain why I'm so slow. I use a HP Microserver Gen 8 as my Unraid box. 1. 0-rc12a below is a chart of my devices and their speeds: backplane ata# sdX device Name Read Write ----- Go to unRAID r/unRAID • by So I recently upgraded my server to a B560 and i5 10400 and since then my UI has been so slow to load. All my components are still the same but added another pci sata/sas expander card. I'm testing unRAID to see if it is a viable replacement for my existing Ubuntu server running RAID 6 using mdadm. There are a lot of helpful people there who can walk you through the debugging process. Solution 1: Setting up an rsync server. When I copy 4GB files to the unRAID server, it starts ok, but slows down to around 36MB/s pretty quickly and there it stays. 5 GB/s average speed for my pool so yeah unraid can do it with the plugin Completely normal to get slow parity checks, especially with those larger disks. Yes, so not your ISP. that is clearly not accurate from the rate data from the cache drive is going down. I have write mode set to reconstruct write (turbo write), so shouldn't be limited by head seek. By steelman1991 January 7, 2021 in General Support. 0. 8. So I needed to get around that crypto stuff. Reply to this topic So I have the binhex-qbittorrentvpn docker setup (using Wireguard) with PIA and this connection is fast! I grab torrents very quickly and have no issues. Unraid uses parity drives, and does not stripe the data. I seem to be getting extremely slow transfer speeds between Windows and the NAS. Upgraded from 6. Reply reply more reply More replies More replies. the other one is a new build and was working great. So, I'm setting up a quick n dirty unRaid to play with Beta 5. It needs to go through all your drives start to finish once but it does so on all drives at the same time so first of all the slowest drives will slow you down in the beginning and the largest drive will extend the time in the end. So, if you have Time machine writing to your TM share, or Crashplan or Dirsync running and causing reads or writes to the array, that Hi, and don't worry, you're good, plus we're a friendly bunch here, promise I'm not that good at such issue as yours honestly, so hopefully others can lend you a hand later, and I also dont really have time now honestly but try other VPN endpoint/country unless you're sure it's a good one you have selected currently, and secondly try disable both 'enable_outgoing_utp' If there isn't then unraid will skip cache and move to array directly, which will take a while, especially if you have parity and Tunable (md_write_method) in Disk Settings set to Auto and not reconstruct write. Product; testdisk to restore the partition and xfs_repair to restore the drive now i got the data back ^^ but i dont understand why on my unraid server it is not working. Assuming that the port and the drive are actually USB3, what are some other reasons for the slow copy? For reference, here is my command: So i have replaced the broadcom cards with Mellanox MCX311A-XCAT CX311A ConnectX-3 EN 10G Ethernet 10GbE SFP+ x2 I have created a ramdisk in windows 10 and also unraid. By that I could test it with different internet connections as well. It's I don't have a test server for unRAID so can only try out these suggestions on a weekend when I don't need my production environment up and running. It turned out that on a laptop with Samsung 980 PRO SSD (NVME variety) the overhead of git status on a huge tree (cromium checkout) compared with raw partition became slower by 15-20% while tar xf that expanded into the corresponding tree became slower by 25-30%. I like it as opposed to ssh and MC for very long file transfers (like 10s of TB) it's so nice to have a quick to call up docker page of a transfer that takes days, gives nice easy to see feedback of the transfer going along. I made change in my docker-compose. . On the Azure VM, it responds in less than 1s. 0 or 3. We have no idea what the OP is doing, but the question is still a valid one. Rsync is not efficient / slow, but rock reliable, So I won't use cache disk ( mover ) for any share due to slow speed no gain overall. ini) because they are files directory most frequently called every time when a Wordpress WhySoSlow finds out why your system is running slow, the serious way. Unraid is an operating system that brings enterprise-class features for personal and small business applications. 7. I really don't know what's wrong with it, but you may want to think about switching to zfs. (2 MB/s over wifi, 35 MB/s over cat5e ethernet cable. I have 64GB of ddr3 ecc memory in unraid server 32 GB of ram in windows machine. conf. Why is VNC so slow? You may wonder why VNC is slow. But this is the first time I've setup unRaid using AMD (ryzen 5 5600x and B550 tomahawk pro) I don't understand why it's happening. I have tried many other nextcloud dockers and they are all slow compared to ubuntu VM. But going from one SATA3 drive to another SATA3 drive, internally should NOT be going this slow. I have been backing up for over 1 months and still only 25% complete. Configure your computer systems to maximize performance and capacity using any combination of OS, storage All Activity; Home ; Legacy Support (unRAID 5 and Older) General Support (V5 and Older) Why is my Unraid file transfers are so slow compared to others? Why is it so slow? /Edit Remember that Unraid's initial philosophy was that it was to be a storage system intended for applications where the primary use was write-once and read-many! Write speed was not a primary consideration in either its concept or design. My Parity disk comes to 265MB/s and my data disk to 175MB/s. im thankfull for every tipp greetings MrYoshii. I have found it to be considerably faster than krusader. Umm, so why does rewinding 10 seconds purge ALL the buffer that my Plex client has spent the last 20 minutes building up? Incredibly frustrating when Most file managers will. Basic Idea: Docker pull and install are slow, performance is bad. Unless you're able to download at more than 1Gb/s you won't notice a difference in download times, and your imports will be instant as you'll be able to utilize atomic moves. d/rsync start exists silently, when rsync is not enabled in /etc/default/rsync. If this is your initial ingest to the NAS, wait to enable Oddly, after crossing about 5. Your unRAID network adapter is gigabit it seems, so check to make sure you are using cat5e or better cables, that any switches or routers in between are also capable of gigabit speeds. Hey unraid friends, so i am a bit amazed as i set up my gigabit internet connection. 10. I have one 250 GB NVMe cache drive and 4 5400 RPM drives (1 So issue is isolated to my current Unraid box. Just set up my first NAS, using UnRaid. I would like to continue use the cache disk, because it keeps all disks spinned down during scattered downloads over the day - but i agree that performance wise the slow mover performance kind of defeats the idea of a cache disk. So unRAID is only using your onboard NIC correct? If so then that is exactly what I am doing. I run on Unraid. I have 22TB of data I’m copying from my local LAN to LAN unraid to unraid machines. For now, I'm going back to 6. We all talk about using an array for redundancy, performance, scalability so why would you put all Once in Unraid, I had to reconfigure the network settings since I left the Intel LAN controller enabled, then rebooted Unraid to save the changes. It sat for over a year in storage, but after setting it back up and such, i decided to upgrade it from 6. The crypto makes it slow. You are thus getting constant head movement back and forth on the parity drive between the sector(s) involved in the write and the sectors being accessed by the current position of the parity check process. data transfering is very slow only at 4 to 11mbps only, even when i opening any file from server its also taking too much time snooky-diagnostics-20230626-1621. Long Version: I had noticed that the docker containers performed slowly. png") and all of them seemed slow. Array accesses are what slow things down, so unless you have your Docker image on the array or they access stuff stored there it won't impact things. 2 (can't believe I forgot to put that in). I'm assuming you use SABnzbd 3. If they did, then the people who I've noticed my unraid server is very slow to update docker containers. Note as I changed the short syntax to long syntax. – Zero the drive so that it will not affect parity (only really important when you already have a parity in place and Unraid will do that too when you add a new drive to your array) More importantly, it will check your drive by reading the current state, zero everything and then read it again to confirm that everything was correct. 12 to gain the newer features and such. But copying a completed file from /Downloads -> /Media takes forever. Gonna be a game changer if they ever go mass market with Don't feel bad. yml. Hope that helps Anything reading or writing to the array disks will slow down a parity check. Running on Unraid like Op so a little different but from the command line (if that’s how you are creating) add the option of --dns=8. Version. Either WebGUI is super slow or something is going on that makes the server itself slow Either WebGUI is super slow or something is going on that makes the server itself slow So, I'm thinking maybe something hardware related, but I was hoping it wasn't. v1. to see if it deletes it Hello All, So I've been chasing down some issues with my unRaid server lately. But one thing has me bugged beyond anything, Hyper slow transfer speeds. that transferring files to the main array can take No the MacBook Pro and Unraid Server are both in Spain, while the Mac Pro is in Los Angeles. Any ideas? Takes 15 minutes and its up and running with better performance than ever before. All this is very far away from my knowledge area so probably I'm making a dumb mistake here: I'm getting 10 to 11MB/s file write speed from windows to the server. I tried transplanting the drives in a different server but still had the same Issues. What I am confused about is, why is the connection over Wi-Fi so slow when transferring stuff internally compared to just accessing the net where things are super fast even over Wi-Fi? Thankyou, Neil Legacy Support (unRAID 5 and Older) General Support (V5 and Older) I need help finding out why rebuild is so slow [solved] I need help finding out why rebuild is so slow [solved] By hellow August 16, 2014 in General Support (V5 and Older) Followers 1. How can I make the networking in my container faster? network-programming; docker; dns; Share. Downloading a high bitrate film to an iphone takes forever (more than an hour), apparently due to Plex transcoding it very slowly. That is the tldr; Commented out the DS_Store veto files line from Unraid -> Settings -> SMB -> Extra Configuration section and removed the /etc/nsmb. The problem is that the copying is very slow - around 30MB/s. Thanks to u/GuilhermeFreire for recommending LibreSpeed docker. zip When you transfer files to your Unraid server for a cache-enable share, the files are written first to the cache drive. Reply reply silentheaven83 • I formatted all of them with “destructive mode” before inserting them into the array. 9 to 6. The service it connects to expects responses pretty timely, like 5s per request and it's just too slow to deal with that so ends up getting hit with retries that cause further issues. It's so slow it might even be real time, i never This will require a deeper analysis. Downloading from unraid to my main pc is transfering a file at about 120MB/s so seems the issue is unraid networking from here on. so but 1 after the other: My downloads folder is set up like this and has cache drive enabled data transfering is very slow only at 4 to 11mbps only, even when i opening any file from server its also taking too much time snooky-diagnostics-20230626-1621. I'm evaluating it at the moment, to see if it will suit my usage. I suppose limetech could implement the logic needed to force the write to cache so the mover will put it back on the array later, but they haven't. 8 For those searching this issue, I have also resolved slow speeds by adding the DNS entry. If you want to perform SMB file transfers over LAN (we do not recommend you By slow unpacking, we're talking over a day for a 50-70GB series pack. Hi, I searched in the forum but did not found any solution for the problem so far. What are some causes and remedies to speed up the UI? My internet isn't the problem either. I'm not sure why, but I'll take it. In earlier Unraid versions (Samba version has to support vfs_fruit), this has to be done manually in the smb. Whether I'm downloading one torrent or multiple torrents, the total dl speed is always around 100KB/s. Guys, read manual and don’t tell this stupid things about ssd cache. Docker service poor network performance. I am also seeing more normal CPU utilization (~20%, no cores maxed). 61 WhySoSlow does a serious effort at analyzing your system to find out why it's running slow. I was careful to not switch back to the unRAID console input on the monitor and to watch preclear progress and performance through unMenu. I am copying my files from another drive, mounted on unRaid, I have spent the last 8 days trying to transfer over 9tb of data, from my old windows rig to the unraid server before formating my pc. The same behavior happens on the Main array tab, the other main pages seem to be unaffected. It could be several things which are causing this. Unfortunately (I guess depending on your perspective) this did NOT fix the issue. I'm using version 4. 7 to avoid slow SMB and the concurrent disk problem in 6. I'll keep monitoring this for a few more hours, and will mark this solved if the slow parity issue doesn't return. RDP is a only reasons why millions people still use windows because linux just still suck. The fact that it switches between cores is also totally normal. I very strongly doubt that parity calculation is multi-threaded on unRaid so it pegging a single core is totally normal. But I've always had an issue with Parity running slow. 5% parity check completion, the parity speed has returned to normal levels (currently ~142MB/sec). I'm not 50 to 60MB/s are the normal unRAID writing speed due to how parity works with the default settings, you can enable turbo write for faster writes. 15. Install Overseer on UnRaid Having some slow transfer speeds on my unraid server and was hoping you guys can lend some insight. Light Mode Dark Mode. With that These folders map to a SATA SSD on the remote server, which is running Unraid so Mover will eventually get it to the SATA HDDs. 8 This is faster than other preclears using the MB SATA ports. 3. However that shouldn't come into play here as it will download to the cache disk first and then run mover in a few hours or overnight. If so, is there any way to fix this? Or steps to figure out why its so slow? Edit: Once the container is started though, the container itself is fine. I've tried downgrading to 4. • starting up dockers • Due to several reasons, the HBA doesn't have a faceplate, so the card is held in solely by friction. 5 - now experiencing slow SMB responsivity. I updated my hardware a few months back and just setup a new unraid server on my old hardware as an off site backup unit. This is the only docker that behaves this way. Hey, first time poster so please be gentle with me. I added wp-content and php-conf (to get php. So if I download something I want to watch right away it takes a tediously long time to become available in Plex. This week I set up an Unraid server for the first time using the same hardware (but new hard drives which I moved the content on to) and set up Plex using the binhex docker. ) I have two unraid boxes. I upgraded to 6. Most people are storing movies, music, photos, video, backups on unRAID. One is working fine - everything reacts quickly. I'll have to check the settings on unraid to see why its not going over 1gb speeds. It seemed as if it would get up to 25mb/s and then suddenly drop down to around 17mb/s and then climb again. ParScan- ??? When I was using ZFS on unraid I reached a 9 GB/s scrub speed with a 5. Have been using it for a week. When the mover is running Unraid becomes very slow to a point where I have to wait 5-15 minutes for the webUI to become available and it takes the same amount of time for any action there. proxy. The Rancher appdata is running off of a NFS PVC provisioner that's mapped to an appdata share/folder that Hello, I am having a rough time with the mover. I love everything about unraid so far. Curious as to Unraid uses KVM for vms, so there is a full type 1 hypervisor running under the hood, that gives basically the same vm performance as all other commercial hypervisors. 2 and later, there is a GUI setting to improve macOS connection behavior via the underlying Samba service config. Is this forum hosted on AWS, too? This would explain why it is somethings so extremely slow. 250mb up and down, 10ms ping, was able to ping I can’t figure out why my Unraid SMB shares are so painfully slow at ~10MB/s with an SSD cache. It's painful to I installed unRaid yesterday, and despite its very nice features, it is extremely slow when compared both with Proxmox and TrueNAS on the exact same system. Another thing that definately helps is to mount the SSD directly, rather than mounting the unraid share. conf files from my Mac and I was able to achieve gigabit SMB speeds from Unraid to Mac. Why copying to array so slow - because data will be verified on the fly. 2. The mover also seems t I recently upgraded my unraid server, and the first thing I noticed was that all my docker commands are responding VERY slowly. Longer copies, those in the 20GB range, often slow down to 70TB over time. All of my networking is at least Gigabit. Followers 1. you will need manual backups in that case. They kept saying they thought my drive would fail before parity was built and id loose all the data so was better of trying to use unbalanced and copy all the data, then ad parity and then remove and replace drive but it didn't fail it worked fine. now all of the sudden it take a long time to do anything. In the meantime, if there I'm a new unraid user. zip Hi, and don't worry, you're good, plus we're a friendly bunch here, promise I'm not that good at such issue as yours honestly, so hopefully others can lend you a hand later, and I also dont really have time now honestly but try other VPN endpoint/country unless you're sure it's a good one you have selected currently, and secondly try disable both 'enable_outgoing_utp' The problem is that any writes to the array also require writes to the corresponding sector on the parity drive. Yeah, after going back into it, I think the issue was either power-related (the hot-swap bay only uses two power inputs to power 3 HDDs) - less likely or related to by PCIe-SATA card. (with the CPU). Write speeds are same, but it takes some time to start It had a lot of small files, it may explain why it's slow. I am currently in the process of making an Ubuntu live USB so we will se. Not sure if removing the apps helped or if the cache kicked in just now, but switching to Files again, took 32 seconds to fully load the page and 18 seconds to fully load the file list. I upgraded my hardware from a 9700k to a 13900k and updated unraid to 6. Trying to find why Unraid feels slow. Steps to Reproduce. But still with 150Mbps/10Mbps I am mostly stuck on 2-60Kb/s with often "dropping" upload and reconnecting in a few secs. 13. I'm running 4. I started the preclear from the unRAID server console, switched video input to my desktop and started a telnet session to the server. Speed from the MacBook Pro (Spain) to Mac Pro (LA) are great while speeds from Unraid (Spain) to Mac Pro (LA) are horrible. So lets say I have two shares, share A is set as yes to use the cache drive while share B is set to not use it at all. When you transfer files to your Unraid server for a cache-enable share, the files are written first to the cache drive. 2, 4. This is normal for an unRAID array, data isn't striped, so it's limited to the speed of your slowest disk at the position, for better performance you can create for example a zfs raidz pool, of course it also has some Unraid OS Support ; General Support [SOLVED] Really slow (50 MB/s) transfer speed between disks on UnRaid - Even with parity turned off The source device is an old SATA hdd so maybe that's why the transfer speed is so slow. /etc/init. I guess it could be enhanced (if it has not already) to take account of I put this in general because i seem to have 2 issues but i believe they are all related to linux. so it will be slow. In RAID5, parity is split amongst each drive in the array, so it is also all written at the same time, resulting in high write speeds. I know this is probably going to open up a whole can of worms, but I at least wanted to give people some hope. Hi! Sorry for posting "another slow performance post" but I'm really desperate about this: I've checked multiple posts and over the internet and tested different solutions and can't make it work properly. Still leaning into the iowait time being an indication of something.
