An image-reading tool I maintain works 14 times faster in Python 3.4 compared to Python 2.7. I have no way of accounting for the difference though.

This is probably the first time I heard of such a speedup when going from 2.7 to 3.x, and the fact that you can't account for it makes it worse because we can't evaluate what's happening and if such speedup could be achievable on other projects :(
