Ideally, it should reduce cpu speed to about 20% when speed is not needed, and restore speed to 100% when the load requires it. There is such a utility for Linux, called powernowd: http://www.deater.net/john/powernowd.html Using this with Debian, my cpu temperature drops by about 15 degrees Celsius! I'm just wondering if a utility similar to powernowd already exists for FreeBSD? I did search the mailing list archives and found some talk about developing just such a program, but never found out if it was finally done, and what the said package might be called. regards, Robert
