Controlling laptop performance.

view full story

http://forums.opensuse.org – I'm setting up a laptop as a digital audio workstation. While the audio apps are running, I want to disable any cpu frequency scaling or power management, etc, so that the system just operates at full capacity. I know about powersave, and I can run powersave -f to force full cpu frequency. I will run that as part of my Jack start-up. Is there anything else I can do regarding power management, to ensure maximum system performance? I'm running xfce in this installation, so I assume any tools would need to be cli. Thanks for any suggestions. Paul (Distributions)
