Sorry it's another slow SMB transfer problem... With upload failures

[akc1]

Hi,

Apologies for posting another slow SMB thread but I have used the search and couldn't find anything massively applicable to my situation.

Background: The NAS was working fine on Truenas version 11. something I then upgraded to core 12 and performance has tanked. I was virtualized but have now gone bare metal to try and resolve these issues. I have tried going back to version 11 as well and just can't get my performance back!

System setup:
Supermicro X9SRL-F
E5-2690 V0
96GB Registered ECC Ram
Mellanox ConnectX-5 25Gb NIC running at 10Gb
SAS2308-8I 9217-8I SAS card
6x HGST 7200rpm 4TB NAS Drives
SSD System disk
No tunables and have tried a fresh install

The Issue: Transfers from NAS to desktop seem to start fine then go stop-start-stop-start... as seen below.

It's so bad i can't even stream high quality FLAC files without buffering!

Large files sent to the NAS also fail completely, small files transfer fine.

I have run iperf and get a good 10Gb/s result.

Please help my NAS is pretty much unusable at the moment!

Many thanks in advance,

Alex

Send me a debug via private message System->Advanced->Save Debug.

Hi Anados,

Thank you for your continued help, I was trouble shooting trying different things yesterday and tried a direct connection between NAS and 10Gb client. FULL SPEED! very strange as my switch config hasn't changed that I am aware of. I now believe this to be a networking issue rather than Truenas but happy to send debug if you think it might still be a Truenas issue?
