Often on gentoo related IRC chanels comes someone who asks why his
firefox-bin (or openoffice-bin or *-bin) runs faster than his
built-from-source firefox.

Usually chan's gurus answer that upstream packagers use all the possible
compiler optimizations (CFLAGS LDFLAGS etc.) for the given package,
while the average gentoo users keeps a set of "system wide very safe
optimizations" that are good for most packages, but not the best for
every particolar package.

Is that statement correct?
