LAMP: Linux And Managed PowerLamp logo

LAMP is a simple user-level tool to adapt CPU frequency to CPU load, to achieve a balance between performance and battery life for laptops.

It runs on recent (post 2.4) versions of the Linux kernel.

How it works

LAMP simply follows CPU load. It regularly monitors CPU load (every 1 second), and if this crosses a threshold (50%), it steps up to the processor's maximum frequency. If the load falls below the threshold, it steps down to a lower frequency.
