The comparisions i had where for mklinux/linux/L4 linux and the
mklinux was using the mach 3 that rhapsody uses. mklinux benchmarks where
poor. L4 was a bit better then the normal linux, I can track down the url
if you want. It was on L4's site.

I have a friend with a power pc mac clone who's used mklinux and
is getting rhapsody. Ill ask him if he can supply any benchmarks.
