Do you have the skills to detect and handle if gcc miscompiles something at -O3? If not, then don't.
Noone else will help you getting a zomg-fast -O3 system working after a slight miscompile gets a few bad instructions stuffed into some lib somewhere, so if you break your system, you get to keep all the pieces.
