Stefan Krah added the comment: I'm surprised, too, but after a couple of retries the results stay the same. On an i7 there's also a difference, but not quite as large. I'm using b16527f84774.diff, which applies cleanly apart from importlib.h (which I just regenerated).
With an increased loop count the difference is also the same (10% on the Core2 Duo).
