Also found this so seems I haven’t been the only one experiencing this issue.

Thanks Jorge, Not sure what I am looking at to be honest.

I updated my system and swapped out for a new motherboard, cpu and case. Now I am kind of back to my oringal problem but I am getting 20-25MB/s downlaods Could this issue be caused by a bad SAS to Sata cable? or a failing drive? tower-diagnostics-20230504-1403.zip

Update, for anyone who is curious. I swapped from the nvme cache to a sata ssd and still no change. I have found tough, that when I have 6/8 SAS to sata connectors plugged into my drives I get the poor sabnzdb (docker) download performance (1.5MB/s). But when I have 4/8 sas to sata connectors (I think that is what these are called, I am not quite sure) my sabnzdb download performance is back where I would kind of expect it (50-60MB/s, I have a 1Gb connection so perfect world and originally this was around 90MB/s). I will get around to moving back to the nvme drive, hopefully keeping the status quo and after that I will try test to see if it is a falt with one of my SAS to sata connectors or it could be a fault with one of the two SAS plugs on the HBA board I guess too?

update: Still no fix, I have reformatted all drives to XFS and have moved my cache drive over to a SATA SSD. My downloads still cap at 1-1.5 MB/s when all drives are connected through the HBA card. I still get normal performace when all array drives are through the on board SATA ports and the SATA SSD (cache) is via the HBA card. Any suggestions or ideas?

Fixed up the shares using cache all of a sudden and re-run the upgrade to 6.11.0-RC4. No hiccups this time. Not really sure what happened in the end.

Correct. Sometimes there will be a spike in download speed but these are random and also still only around 6MB/s.

Sab history before switching back to HBA (originally on HBA 3 days and beyond ago). and straight back to throttled downloads this makes no sense haha. There is no other activey on the server.

This is me making the change back to the on board sata ports. I'll lets some more downloads occur naturally and will convert back to the HBA card and report back.

Yeah downloading direct to cache, ran common problems to make sure I hadn’t missed anything. Array writes seemed to be normal. Only really noticed the slower docker update downloads and Sab was clearly slower. Is there any tests I can run on the disk layer that could build more of a picture? How do I convert to xfs and do I loose data if/when I convert? thanks

I have reconnected all my HDDs back to the onboard sata ports and so far my SAB downloads are back to normal, so utilizing the full bandwidth of my internet connection. Looking at the syslogs the HBA card shows up correctly as far as I understand. mpt2sas_cm0: LSISAS2308: FWVersion(20.00.07.00), ChipRevision(0x05), BiosVersion(07.39.02.00) Aug 17 11:42:23 Tower kernel: mpt2sas_cm0: Protocol=(Initiator,Target), mpt2sas_cm0: Capabilities=(TLR,EEDP,Snapshot Buffer,Diag Trace Buffer,Task Set Full,NCQ) attached is the latest diagnostics zip with setup no using HBA. Anyone able to provided some advice? Was i meant to change a setting before installing? tower-diagnostics-20220817-1146.zip

would a HBA card potential cause a slowdown? It might just be a coincidence but looking back, my slowness seems to have started the day I installed my HBA card (LSI 9207-8i) My cache is on an nvme drive.

I have upgraded to 6.11.0-rc2 to see if this makes any difference by some chance. Unfortunately it seems to have made no difference. anyone have any suggestions?

I am in Australia, so not impacted by that outage.
