Woof:
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).

ClassicHasClass:
Interesting observation. I wonder how one could benchmark that.

Woof:
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.

rheaplex:
Which kernel are you using with your 9100? I'm having trouble on anything other than 5.5 .

Woof:
@rheaplex I'll let you know next week (it's at work).
