I apologize if I read you wrong. I will point out, though, that your
concluding paragraph made an incorrect conclusion. You seem to believe
that the tester believes that compiler flags made all the difference.
I do not read the article referred to the same way that you do.

The purpose of the test wasn't to compare GCC optimizer settings. It was
to compare Gentoo to Mandrake. Unless I am wrong, the reason Mandrake was
chosen, is because Mandrake purports to be GCC optimized for the
Pentium instruction set as well... I'm not sure what you would gain from
the test that you couldn't gain from recompiling a few RedHat packages with
GCC optimizer settings finely tuned.
