I'd expect to see some improvement, based solely on the bugs fixed recently by the optimizer team. No idea how much, but I know that Martin builds with PGO, and that's also been improved recently.

No idea what the gcc update involved, but this is only accurate if it took less than two minutes :-) I've upgraded the CPython projects before and everything worked fine.
