"kicks ass" is a relative term. In terms of

And the trade off of that, which is what I'm
getting at here, is that LINUX sucks ass with one
processor. So in order to work well with 4
processors you have to make the OS suck with 1.
More people use 1, so you wonder what the world
will be like with the geeks in charge. You have
to make things worse for most people in order to
appease the few. At least before, you could
decide to use FreeBSD if you had a uniprocessor
system. Now there is no choice at all.
Frankly benchmarks bore me. They don't test real
world things. A machines usefulness is the sum
total of all of the things it must do to
accomplish whatever task you have it doing. A
linux 2.4 kernel will start dropping packets at
1/2 the point that FreeBSD 4 will, so I dont
