Profile Guided Optimization: http://en.wikipedia.org/wiki/Profile-gui...timization

Basically we compile a special build which records whatever happens when PCSX2 is used (not in video, the actual code that runs). Then we use this build to play some games (though it's very slow, so it takes a long time). Then the compiler looks at the recording, and it compiles PCSX2 again, but this time optimizes such that the code which is used most is optimized most, and the end result is the build which then can be published. PGO builds are 5-10% faster than normal builds.

Ah nice, thanks for the explanation!
