In that case, you want to keep all other things equal; so use the same distribution, only with -O2 -march=i686 vs. -march=athlon-xp (or whatever). /* Steinar */
Using Gentoo is just a easy way to make cflag optimizations to all the other libs as well: glibc, ... I can also mesure performance on Gentoo with cflag optimized PostgreSQL and plain PostgreSQL as well.
