Disabling CPU Scaling With Ubuntu 10.04

If your like me it annoys you that your desktop keeps messing with your CPU speeds when all you wan’t is performance. Fortunately its easy enough to fix.

Open a terminal windows and execute:

sudo apt-get update

sudo apt-get install rcconf

(Chances are you may already have the rcconf installed.)

sudo rcconf

Scroll down the list of services till you find the service labelled “Ondemand”, this is the service that controls the CPU scaling. Unselect the option and hit Ok to exit, now when you reboot your system should run at full speed all the time.
