“… Clock scaling allows you to change the clock speed of the CPUs on the fly. This is a nice method to save battery power, because the lower the clock speed, the less power the CPU consumes. The CPUfreq governor “performance” sets the CPU statically to the highest frequency within the borders of scaling_min_freq and scaling_max_freq. …”

 

Centos 6 in /etc/sysconfig/cpuspeed –

GOVERNOR=performance
# watch grep \"cpu MHz\" /proc/cpuinfo
