I'm well aware of that, no worries. M2 PCIe is PCIe 4x4 per slot, so 8GB/s per slots, which is more than enough. With 3 slots it's 24GB/s (in theory). If you add an additional NVMe plugged in a PCIe 4 16x slot, it's now 4 NVMe, each working at PCIe x4, so 4x8 = 32GB/s max. This NVMe is announced...

In order to advance on this strange behavior, I experimented a lot, here is what I can tell you: On the exact same system (so no hardware changes at all, no new pool creation), using the same test method with files bigger than ARC : With FreeBSD 14 RC1, I got better internal performances when...

I just tried with a 20GB ram disk, shared it, and got 2800MB/s in read and write. So, as far as I can tell, it doesn't seems to be a SMB performance problem.

I'm actually trying to set up a high-speed samba share over a 40Gb direct connection between a Windows 10 system and a FreeBSD 13.2 server. Regarding my network setup, I'm using two Chelsio 40Gb T580-LP-CR. Doing an iperf test between these two systems give me 35Gb/s with single thread and...

Thanks a lot ! Which Linux distribution do you recommend ? I'm mainly using OmniOS and FreeBSD for ZFS, and don't have any experience with Linux kernel for ZFS ?

Don't know with which consumer drives you tested, but I can assure you after hours of testing, the 990 pro don't fell flat at all. I did a more than 1 hour test with TBs of data and never got a single drop of performance on these drives. If you're referring to write performances, I already know...

FYI, my 990 didn't throttle due to temp. As stated, doing test on a single pool gives me 13GB/s. I can do the test on two pools then on one, and I always got 13GB/s. So I got different behavior when doing do the same test. Even with my SAS SSDs pool I got this bottleneck behavior, so it's not...

Ok, great to know ! This means something is actually wrong on my system, I have to find out what. You got that on FreeBSD ? I'm wondering if using a Threadripper pro 5975WX can be a viable alternative to the Epyc 9374, what do you think ?

Did you already achieve this type of performances ? If yes, can you please share your config and tuning ?

990Pro Nvme won't be uses in production on this server, they're only purpose here is for testing without any additional hardware. In fact I also got 12 Samsung PM1643a in SAS, but I discovered one of my SAS card, a Broadcom 9500-8i was defective and I'm waiting for its replacement. As I'm...

These SSDs are connected using the motherboard M2 slots (Asrock TRX40 Creator) and PCIe gen4 x16 to single nvme adapters. I tried 3 SSDs on the motherboards, as it has 3 slots, and one on PCIe, or 2 on the motherboard and 2 on 2 PCIe slots, same thing. About the fact ZFS is not a performance...

Hi, I'm currently trying to get the best performances I can on FreeBSD with NVMe drives, in order to know how many servers my workflow is going to require (reading a lot of 60MB dpx files per seconds). For testing purpose, I'm using 4x 1Tb Samsung 990 Pro on a system equipped with a...

Ok, too bad. I didn't know if you used a modified version of mini_httpd or not. I will test Apache version asap! Thanks a lot for your work!

Hi Gea I just saw your post and was wondering if it was possible for you to use the latest version of mini_httpd (1.30) which is working well in https instead of the 1.27 you're actually using? FYI, I tried to use mini_httpd 1.30 instead of napp-it-mhttpd, but it's not working properly. I can...

Hi Gea, I've made tests on a second server, using 3 bakcplanes of 15 disks each, each backplane connected to a different SAS port on a Supermicro AOC S3216 HBA card. Napp-It version is 21.06. When I issue the command echo "::mptsas -t" | sudo mdb -k to get disk info without sasircu, I got...
