Static linking (with link-time optimisation) allows for nice compact code that cold-loads very quickly. There is a lot to be said for static linking.

Note that we're not building with PGO on Linux or OS X right now. Last time we tried it it wasn't a big win, plus it always seems to hit GCC bugs. Visual C++ PGO does do block reordering:
