In the old centos 4 we had cpuspeed and we could send a SIGUSR1 to it so the CPU would run at max speed. In centos 5 cpuspeed is not running. (although running with cpuspeed -C will go full speed) what is the correct way now in centos 5 to on the fly say run at full speed then sometime later tell it to drop back down? I have no process to signal any more. Jerry
