As far as I understand, the main problem with Phoronix's test suite is
that it doesn't use native packages.
Sure, Phoronix' copy of bzip2/apache/etc might be slower on Fedora 11
compared to Fedora 8, but it more-or-less says -zero- about the actual
performance difference between the -native- versions of bzip2/apache/etc
on Fedora 8 and Fedora 11. 

I'm not saying that Phoronix is wrong - I am saying that his testing
methodology is invalid.
