Well it's a Dell Optiplex 330, Intel G31 Express chipset. I looked through BIOS- I couldn't find anything to disable that might be system management interrupts.
With Linux localhost 3.2.0-4-rt-686-pae #1 SMP PREEMPT RT Debian 3.2.78-1 i686 GNU/Linux, still have onboard video, browsing the web and running bittorrent: Servo Thread Max Interval 1,217,422ns Max Jitter 217,422ns Base Thread Max Interval 199,820ns Max Jitter 174,820ns There's an optiplex 360 with G31 chipset result here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test They got: 1,010,913 16,443 39,908 14,966 So that jitter's WAY higher on my 330. I know the onboard video can add to it, but can it be THAT much? And it's beside the point because that other guy's test says "Intel G31 onboard Video. SMP Kernel "... those lower numbers were ALREADY using a video card. I can add a video card, got several lying around, just a good amount of installation time really.
