well, more to the NT guys, back in the old BSD days we rebuilt kernels as well.

we had a Dual PPro200 setup a couple years ago that could tear through an
entire 'make world' in FreeBSD in under 20 minutes.  it has more to do with
the way you layout the disks than it does the CPU power.

because SMP support on a Uni-processor machine incures overhead that doesn't
need to be there.  i've done (and i've seen other people do and populate web
pages with info from) testing proving that running an SMP kernel on a non SMP
box is a huge waste of clock cycles.

although the copy of redhat we had at half.com came with both an SP and MP
kernel (that didn't stop me from rolling my own though)
