Slightly better

	chkconfig --level 123456 cpuspeed off

If you stop in level 1 for some reason cpuspeed
can clock down the CPU then 'telinit 5' and
you do not have cpuspeed to get you out of first gear.
(what is a Nash Rambler ---).

For most of us "chkconfig cpuspeed off" is just fine.

Watch our for 'micro' benchmarks of any kind.
They often do not run long enough to be noticed by cpuspeed.
