there is a correlation.. to a point. once you're down to 30msec or so (depends on the cpu, for some it's 10msec already) the incremental power gains are pretty small. That is for todays cpus.. future will change. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
