I think the lack of performance gains may have to do with the actual build environment... but I don't know. I know for a fact that Gentoo Linux compiled with the options I am trying to compile these rpm's with, is a good 20-40% faster. Especially at things like opening konqueror, mozilla, and X so we'll see
