You should stay with the ondemand governor, you will not see any difference, except on yout electricity bill (and on the environnement too). Anyway, just edit /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and it should work. (as root : echo "performance"/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor)You may need sysfsutils to set it up at boot time : edit /etc/sysfs.conf and write : devices/system/cpu/cpu0/cpufreq/scaling_governor = performance Best Regards.
The folks over in #vmserver on freenode say that the frequency scaling messes with the timing of the vms. I can say from my tests so far, this seems to be true. With ondemand my vms seem very sluggish taking up to 30 sec just to run a single ping command on the local net (not timing out, but just to run one ping and get a response) With performance, they are merely slow. So, I think I really need to switch to userspace and manually switch to full throttle when I need to get vm work done.
