what is the correct way to set an AMD64 CPU into performance mode at 
boot time?

I have tried doing service network cpuspeed start, then killall -SIGUSR1 
and this works but I cant get it working this way at boot. I have set 
chkconfig cpuspeed on but that
didnt seem to help.

I just want this particular machine to boot in performance mode and stay
