In older version of centos there was cpuspeed -d running that controlled current speed.

In centos 5 it is set for on demand and cpuspeed is not running.

I can startup cpuspeed and send it a signal SIGUSR1 to go full speed. This works.

However, What is the correct or prefered method to control the cpuspeed in centos 5?

THere are times when I want to tell the machine to go full speed and other drop back.

THanks,

Jerry
