i wouldn't suspect that one would want to.
the higher clock rate allows more precise
scheduling. the extra overhead should be
unnoticable on a 2.6ghz processor, except via
stats.

i would imagine that you're getting this kind of
interrupt load from the nic because you're getting
a lot of packets.
do you suspect the interrupt load is a problem, or
are you just bothered by stats?
