If you are running FreeBSD 5.4 or better: You will probably want to set these variables in /etc/rc.conf: performance_cx_lowest="HIGH" # Online CPU idle state performance_cpu_freq="NONE" # Online CPU frequency economy_cx_lowest="HIGH" # Offline CPU idle state economy_cpu_freq="NONE" # Offline CPU frequency The one you want is: economy_cpu_freq="NONE" you will change it to something like: economy_cpu_freq="HIGH" -- ------------------------------------------------------------------------ Eric Anderson Sr. Systems Administrator Centaur Technology A lost ounce of gold may be found, a lost moment of time never. ------------------------------------------------------------------------
