I get the feeling that most of us (myself included) rely too much on the 250 IOPS value used as reference in iX's ZFS Pool White Paper, so I wrote this bit in order to clarify things a tad. IOPS stands for input/output operations per second and represents how many read and write operations a...

This amazing document, created by iXsystems in February 2022 as a "White Paper", cleanly explains how to qualify pool performance touching briefly on how ZFS stores data and presents the advantages, performance and disadvantages of each pool layout (striped vdev, mirrored vdev, raidz vdev). It...

I am needing a storage device to store our backup data on. The application I will be using is ARCserv which does a backup and then just keeps that original full and adds on the incrementals to make new fulls that will be backed up to tape on a weekly basis. Since it will be using the original...

NOTE: I'll be referring in this page, to a type of SSD developed by Intel and Micron, called 3D X-Point (pronounced "crosspoint"). It's most widely sold as Intel's Optane. The Optane devices I mean are things like the 900p, 905p, and P48xx. First generation optane and some smaller ones aren't...

Hello *, for some reason my NAS gets slower and slower the more files are stored in the directory I want to read. If there stored more than 2000 files, it becomes so slow it that working is no longer possible. (You have time to drink a cup of coffee.) I don't think the network is the reason...

I'm setting up my first FreeNAS and doing performance tests of SMB shares. If I read or write, from Mac or Windows, a single large (6 GB) file, I get between 80-110 MB/s, which seems to be what I'd expect. But if, instead of a single big file, I test with a big folder with many files, big and...

Hello all, I'm facing an issue that I don't know if it's normal or not, and Google didn't give me any good results. If I copy a file from my NAS, I get around 115MB/s via Gigabit Ethernet, fine for me. However, if I try to watch a movie from the server (with a bitrate of 200Mb/s - megabits)...

Hello, I am new to FreeNAS. Currently using 11.2-BETA3. No jail, no VM, just windows file sharing on RaidZ2 with LZ4 compression on. I have to physically put the box in a separate room in my home in order to have cable access to my TP-Link WR840N router. My house is an old one and there is no...

I have set up a freenas 11.1-U5 with i5 7400 CPU, 16G RAM and 5 HDDs. For my windows 7 is using ASUS vivo pc with i3 3217U and 8G RAM. When I tried to retrive a 11GB file from NAS, the windows task manager and progress window show almost 100MB/s(Giga LAN). I recently set up another PC, i5 6400...

I have this MacPro 3,1 with a Xeon E5462 2.8GHz Harpertown cpu. The E5462 doesn't have AES-NI. Its currently running 11.1 U4. I'm considering encrypting my 6x1tb RaidZ2. Currently there is no data on it as this was just built a few days ago. Thoughts on performance, etc. I'm using a Dell H310...

Hi all, After a reboot, I'm getting the following messages in the log. I tried to add "txscum tso4" to the network adapters' options, but no change. I assume this is a reason why my performance is roughly maxed at 3.75G with my 10G Chelsio S320-CR. This is the ifconfig output. cxgb0...

Hi, I am new here without any deep FreeNAS knowledge. We are developing opensource storage monitoring tool and wanted to add FreeNAS by using REST API. However we cannot find performance metrics we would expect in REST API (v1 or v2) We would expect per protocols stats (NFS/iSCSI/SMB). This...

Hello, I have few questions before starting with Freenas, I also have been working with other NAS OS and wanted to try this ones. First of all, I just wanted to know If I can achieve with raid5 of 5 disks for example, a write and read speed of 10gbps in disks, I am not talking about that I will...

Hi, I'm new to FreeNAS. Over the last couple weeks I've been tinkering with it and trying to tune my system. Let me describe my equipment: Dell PowerEdge R720xd 12x LFFE5-2690V2NO DUAL INTEL XEON PROCESSOR E5-2690 V2 TEN CORE 25M CACHE 3.0GHz 128 DDR3 ECC RAM 2X Seagate IronWolf 8TB NAS Hard...

.Hi I have some windows Bhyve vms running, which is extremely slow while using the Explorer navigation. When I monitor the resources I see no spikes in CPU usage(1-4 % usage) and memory around 1.5 GB on the Windows 2016 Servers. And nothing to see on network either. I have tried the...

I'm very new to FreeNAS. I have a server setup and running configured with Plex Media Server & SMB sharing. Every so often the server runs very slowly for a few days and then it's fine. When it's running slow the HDD & CPU usage are pretty much constantly at 100% but I have no idea how to check...

I've got two volumes on the same FreeNAS 11 box that use HDDs for data storage: -- #1 is a 2 drive mirror using 5 year old WD Se 4 TB HDDs (WD Se was the predecessor to WD Red Pro) -- #2 is a 2x2 mirror (like a RAID10) using brand new WD Gold 10 TB HDDs Both are set up the same way with full...

Hello everyone! I am troubleshooting a FreeNAS performance issue and was hoping someone out there could provide insight. First, here is my single zPool setup: pool: zPool01 state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM zPool01 ONLINE...

Hello FreeNAS forum. I've just assembled my first FreeNAS box "on a budget" and I was hoping to review the specifications and current performance metrics to see if there is any obvious small or inexpensive tweak that can be made to increase performance. Here is a bit about the hardware...

I have a newer, HP ML10 server with a couple of LSI SAS2008 cards connected to an external case full of newer 2TB to 6TB drives. Pool is organized as 5 vdevs of mirrored pairs. I have a very old IBM rack server at another site with two of the same LSI SAS2008 cards and I use zfs replication to...

I'm getting poor performance from a system that's been installed for about 1 year. In Vmware, when I copy a ISO from one drive to another 1 get 40Mb per sec then slowly it degrades to ~25mb per sec. Potential Problems - ?? - I see that there are 650 Processes in Reporting > system >...

Hello FreeNasers, Short story : I upgrade my NAS from a RAIDZ1 with 3 disks to a RAIDZ2 with 5 disks (adding 2 disks and rebuilding my pool). The bandwidth was downgraded from 110 Mb/s (Ethernet limit) to 70 Mb/s. Long story : I've build a previous FreeNas with low cost hardware (16 Gb of RAM...

I noticed an issue with my rsync speeds to my RAIDZ2 pool. I typically would've gotten 50MB/s but now I can barely write more than single MBps. My pool is nearly 100% capacity so I expected some performance degradation but I still have 150GBs of free space and not for my performance to fall...

Hi, I drive with 6 disks of mirror and got good performance every disk write 200MB per sec but when i add 6 disks to it, it only writes 60MB per disk. dd if=/dev/zero of=tmp.dat bs=2048k count=150k Check my signature for the hardware. Version: FreeNAS-11.1-U1 They are in the same pool and...

Hello everyone, I recently rebuilt my FreeNAS server out of real server components. Everything went fine from pool creation to L2Arc (i know that it may be overkill) and bhyve VM creation. But I now have the following scenario: Transfer from my PC to my NAS is running at around 400-500 MBit/s...

My NAS hardware and tunables are below, and it's a good build. In theory the pool should be blazingly fast, but it isn't. A first bottleneck is that it crawls (comparatively speaking) on sequential writes, even locally from the CLI. I think I know why, and I'd like to reduce the bottleneck...

Hello everyone, I would like to know what is the current support like for the HGST Ultrastar He12 (https://www.hgst.com/products/hard-drives/ultrastar-he12) with P/N HUH721212ALE600 or LE604. I am building an ~100TB storage system for a client in the CG/Animation space using Quanta D51BV-2U...

About a year ago I noticed a drop in my SMB share performance. If I recall accurately, at the time I didn't think much about it as I had just updated FreeNAS to the latest release (I think it was a minor release update, like 9.10-Ux to 9.10-Uy, but I'm not sure). I had assumed that the L2ARC...

Hello all, I'm seeing a weird issue with my 10Gb adapters that I don't really know how to debug. I have the following setup: On Freenas I have an Intel X540-T2 adapter linked directly to my desktop using a good quality 10m CAT6e cable. The desktop uses the Intel X550 adapter onboard the Asus...

Hallo, ich suche nun schon seit Tagen nach einem Perfomanceproblem im Zusammenhang mit Veeam und Freenas. Ich dachte zuerst daß das Problem von Veeam her kommt, es scheint aber dass der Freenas zu langsam ist. Ich habe einen Netgear Readynas 4200 mit der Freenas 11 Stable installiert. Daten: *...

I'm preparing to use an all-SSD FreeNAS server I just built in a QEMU/KVM cluster for use as iSCSI storage. Before I do so, I've been running some performance tests on various types of ZFS pools. The SSDs I'm using are 1 TB Crucial MX300s. According to Newegg, The read/write spec listed is...

Hi all, I've been wandering on the forum for some hours and read a lot of posts regarding write speed, but was not able to find something to point me in the right direction. First my build: HP ML110 G9 Build FreeNAS-11.0-U1 (aa82cc58d) Platform Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz Memory...

When I make terabyte-sized changes so I can see how replicate performs, it doesn't perform as well as I expected. My source and target machines are connected via Intel 10gb connections. iperf tells me that I can get well over 9gb/sec. My replicate goes from 1gb/sec to 1.5gb/sec. I'm not sure...

Hi I am trying to use FreeNAS 9.10 in ESXi 5.5 environment. To check the FreeNAS performance I installed on the same ESXi host 3 virtual machines: WIndows server (for tests), and 2 servers as iSCSI targets - Windows 2016 storage server and FreeNAS 9.10. I configured iSCSI targets on 2016 storage...

Hi FreeNAS forum :-) Another FreeNAS+NFS+ESXI+Datastore performance problem. Thanks for a great forum. (sorry for my english, hope that you understand) First of all, I have read the many threads about NFS Performance with VMWare, and I know and get that it is all related to the SYNC writes...

Bonjour à tous, je me lance dans l’aventure FreeNAS et donc dans le choix des composants. L’utilisation sera la suivante : J’ai 4 TV et 1 Vidéo-projecteur (Salle dédié) possédant tous un lecteur Multimédia (PopCorn Hour A500). Je souhaite faire 2 HDD miroir pour le stockage de tous mes MKV...

Hi all, I've been breaking my head on this case, researching heavily for a good 40+ hours. I finally decided to reach out for help. TL;DR; Getting 60-100MB/s read over iSCSI dual direct wired Intel 10GBE, when we're expecting 500+MB/s read performance. I inherited this [unique?] case on a...

I'm not even convinced that SSD caching is a best practice first off, so here's my --possibly stupid, but please humor me-- question: Say I have 12x 2TB hard drives on my volume (the type of raid here doesn't really come in play with pertaining to the question, but say I use a RAIDZ2 -- being...

Hello. First time poster here on this forum. I've been using freenas on and off for quite a few years and moved my home storage array to freenas full time now as my sole array. Looking for some help with figuring out what or even if something is in fact wrong with one of my pools. If i posted...

TL;DR: FreeNAS is only transferring at a few kbps making replacing disks almost impossible. Hi All, I got freenas running on a dedicated PC (4 core avoton, 32gb ram) and after struggling with a bunch of disks that prevented the OS from booting (no idea why, i just removed them) i got it to...
