Right u used a Gigabyte nuc one.. This is a cheap chinese one with 8Gbs of ram but still, good numbers. that max jitter is maybe so so, but if using a mesa card i think it will be fine on a plasma machine. =)

In general all power management needs to be disabled in the BIOS setup for decent real time performance.
That includes clock speed switching, C states above C1, AMD Cool and Quiet mode etc etc

I think you still have a useable machine for a Mesa ethernet card. It would be interesting to try Chrome instead of firefox.

Your suspicion were right, with Google Chrome max jitter never went over 58.000, but with Chromium the free version it went above 200.000 and firefox about 105.000. =)
