Of course not, this is Gentoo. :)
That's not as much a joke as it sounds like. People who are truly interested in implementing high performance systems occupy themselves with writing and running benchmarks and other analysis tools. When they find issues, they document their findings and (hopefully) submit patches to the appropriate software maintainers.
People who just want to play with their compiler switches and talk about the need "to eke out every last bit of performance from hardware" without actually doing the hard work? They run gentoo.
