Don't use Gentoo because you think that compiling from source code makes it run faster. That's a load of crap because GCC isn't really an optimizing compiler. Infact, I remember seeing some benchmarks where Gentoo, compiled to be platform specific was slower than another distro compiled for i386, or perhaps it was vs Gentoo compiled for i386. You use Gentoo because of the user and support base, the cutting edge packages and Portage. I tried Debian and I tried to like it, but I missed my USE flags in Gentoo.
