This is probably not that likely, but if cpudyn or powernowd or a
similar CPU clock throttling daemon is installed it could be due to
that.

Mind, during an install of Gentoo, you'd expect the CPU to be working
quite hard and these daemons shouldn't be getting in the way of that
(even if they are installed).

It's probably more likely that the fact that it is (was) Thursday is
causing the problem.

I just had a quick Google and it didn't turn up anything relevant. 
Perhaps Gentoo have a bug filed for this?  Perhaps it would be an idea
to try out a benchmarking program to see how much juice Linux is getting
out of the chip.  I did notice some issues involved with APICs being
enabled/disabled on SMP systems, maybe it is related to that.

bye just now,


P.S.  I find this quite ironic, because all day long I have been trying
to slow down my laptop's CPU and it isn't playing :-).
