Update: so the problem appears to be with smbd. I have just rebooted so I will need to let it run for a couple of days again to slow down. I will post my testing results and do some tweaking to see if I can't fix the problem. In the meantime, I'll just use nfs (media share) and afp (hackintosh workstation) for my primary needs. There is only one pc running smb and it's just for incremental backups, so bandwidth there isn't crucial. Will continue to update for the purposes of any user reading this who also encounters this same issue.

Ok, after doing fstrim speeds appeared good on unraid running locally (duplication copy), but network drives no change. But, after smb stop and start, and stopping and starting the array, then unmounting and mounting the drives again, back to normal, so fixed somewhere between that. Will wait for it to slow down again and then test it step by step to find exactly where it is. Thanks all for the input, I will post the results in case someone else has the same issue.

Hmm will try that Glenn, good idea. I didn't think of that. Will let you know how it goes. Thank you for the suggestion.

Hi, The first screenshots are from Unraid to the client (FreeBSD copied to the client machine), and the second screenshots are from the client to Unraid (highsierra.img copied to the Unraid share). Unraid is accessed via SMB in both cases. The test is the same on Windows, and the clients are wired/lan. The problem appears after the server has been on for a few days. It runs perfectly for about a day or so, then gradually slows to a crawl. Thanks.

And after reboot it runs like this.

Also here are the latest diagnostics. beemoth-diagnostics-20191104-0558.zip

Hi, Did this, gave it time, still does exactly the same thing. Slowing to a complete crawl again after some time. Can anyone offer some help? Thanks.

Hi all, Having a really weird problem with my Unraid array that I just can't put my finger on, and I'm hoping someone will be able to help out. The array runs perfectly for the first day or so, then begins slow down to a crawl, running at between 2 and 6mb/sec. The syslog is showing drive errors, which I realise is Unraid being incapable of spinning down SAS drives, and another feature of the SAS controller that Unraid cannot support. I was running FreeNAS when I first built the system hoping to use Bhyve for VMs, and it ran beautifully, no slowdowns, went for weeks at 100mb+/sec easy, but I switched to Unraid as the KVM VM is much better, and now I'm having a pretty bad time with the actual storage portion of the namesake's purpose. I am temporarily regretting the move, but I'm sure someone here will know the solution In the meantime, I'm stuck stopping the array, rebooting Unraid, then starting the array again, every time this happens. A bit of a bummer. I have tried just stopping the array and restarting it, but it does not fix the problem. I have attached photos of the speed before and after rebooting Unraid. The array is btrfs encrypted. The server specs are: Motherboard: ASUS Z9NA-D6 CPUs: 2 x Intel Xeon E5-2440 RAM: 24GB DDR3 ECC Registered Cache: 400GB Seagate ST400FM0073 SAS SSD Array: 3 x 3TB HP/Seagate MB3000FCWDH SAS - 1 in parity, 2 in array SAS controller: ASUS PIKE 2008 (expansion card) Any help would be greatly appreciated.
