But according to "top", the xservers runs with NI=0. I believe I got rid of the X renicing at the time the scheduler was improved. Nobody played flash games at the time though. I have tried running two tuxracers too, and found this to be somewhat bursty. Instead of the players enjoying half a cpu each (which is bearable at sufficiently low resolution), they seem to get bursts of cpu and short pauses. I never bothered looking more into this as the pci card always hangs the machine after a while when doing 3D. Instead I disabled DRI on that xserver. Stability is more important.
