Up until 30 minutes ago, I was unaware of the fact that they use
test-suite compiled binaries.
Though I'd imagine that in Phoronix' view, having (far) different
compile options in the distribution supplied binaries might generate
invalid results. (Due to missing features, non-standard optimization,
etc)

Of-cause, the best solution would have been to test -both- versions -
read: Phoronix-compiled binaries next to distribution supplied binaries
This should generate far cleaner (and far more interesting) results.

I fear that you're expecting far too much from popular website.
I'd rather see an open dialog between Phoronix and the different
distributions an in effort to gain usable test-data out of their
benchmarks.

Has anyone attempted to start an open dialog with them using their
forums? [1].
At least the past, Micheal (Phoronix founder) was very responsive.

I believe we should praise Phoronix for their work, even if we do not
agree with their methodology.
As I said in my previous post, Phoronix completely changed the landscape
of OSS websites and OSS benchmarking.
