We use Gentoo at SiCortex because we have to build from sources anyway
for our MIPS architecture processors, because Gentoo makes it straight-
forward to express dependencies among packages, and because the
ability to control, for example, compiler switches per-package is
quite useful.

For X86 archtectures, it actually makes a very noticable performance
change (30%?) to use build switches that are appropriate for your
machines, rather than the generic switches chosen by Red Had or
Novell.
