The funny thing about the "Gentoo folks" is, their perceived performance
improvement is not reproducible by all Gentoo folks. After wasting many
hours on recompiling stuff with modified compiler options and a largely
different set of build dependencies, not everyone finds the system to be
"much more responsive". Those, that do, should attempt at proving
performance increases with benchmark studies.
