Debian performance tuning via dynamic CPU frequency scaling

Dynamic CPU frequency scaling (also known as CPU throttling) is a technique in computer architecture where a processor is run at a less-than-maximum frequency in order to conserve power. cpufrequtils is used to control the CPU frequency scaling deamon. Frequency scaling allows you to set the CPU frequency on-the-fly or specify an automatic governor.
