[CentOS] correct way to set centos 5 amd64 to performance mode
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 cpuspeed 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 there. Jerry

So you need to /sbin/chkconfig cpuspeed off After a reboot, the CPU(s) will be in performance mode. HTH, Kay
