I have an odd observation and I'd be interested if others have the same, or it's just a bunch of coincidences. Whilst juggling my PCIe cards around to find room for the Arctic Tern board I moved my graphics card (a WX9100) from CPU 2 to CPU 1, and suddenly the machine feels snappier.
I'm running Debian 11 and CPU 1 appears to be doing most of the work (judging by which runs the hottest) so I'm wondering if that's what makes the difference. I always had the impression the graphics were laggy, but now all of a sudden the system feels a lot more usable. That said, the OS received updates, the internal VGA is now disabled, probably other stuff, and the PSU was replaced (the logs were full of MasterDetectionFailure and I got it down to a PSU fault).

Interesting observation. I wonder how one could benchmark that.
-
I should swap it back in the name of science and see what unscientific feeling it gives me…
I tried a few different AMD cards in the past few weeks too, and wasn’t impressed with any until this happy accident.

Which kernel are you using with your 9100? I'm having trouble on anything other than 5.5 .
-
@rheaplex I'll let you know next week (it's at work).

Thank you! :)

I finally took a look and I'm running with a custom 5.10.92 kernel with patches described here:

This is something I did at the start of the year and didn't realise I was still on the same old kernel. AFAIK this is fixed already in the upstream.
-
Thank you! I’ll try and target that. Have you made any changes to the skiroot kernel, firmware, or configuration?

Only rebuilding the kernel with patches. I've been lazy and plugged in a VGA to HDMI adapter to see the BMC boot, so never got round to what should be the next steps.
