Savepower

Update: December 28th, 2011

Savepower is a simple and effective daemon for the cpufreq userspace governor. It is designed for workstations, where all actions have to be done at fastest speed and also after some time of idleness maximum power savings are desired.

Therefore it behaves in following manner:

  • The cpu clock goes immediately up to highest frequency on busy cpu.
  • The cpu clock goes down to lowest frequency after some time of inactivity eg. 15s

The polling frequency is 1s and can be easily shortened.
