I have been thinking about doing the same (at least, recompile kde, qt, postgres). Gentoo users insists that recompiling gives a big perfomance boost. A friend made a test comparing Fedora against Whitebox and get amazing results running sql queries agains Postgres. But somebody told that sometimes, recompile would just give a slower package. -- ru guo ni yao ai, ni jiang bu hui shi qu
