Colm is correct lads.
I used gentoo optimised to bits on a p120, and noticed a decent increase
compared to RH / Suse.
I moved to athlon-xp and was disappointed with the perf gains. There was a
very slight gain, but nothing significant.
And wasted CPU cycles recompiling every update that comes in, we all know
how often updates arrive.
Doing this for an already optimised arch is a waste of time.
Gentoo precompiled would be fine though.
