FWIW, for our web stuff I've found PyPy to be about 3X as slow as CPython (even allowing for the JIT to warm up). But the elephant dances!

Any clue what's taking up the time? Do you think it's simply that it doesn't speed up zope.interface to the level of the C version? I vaguely recall something about PyPy's JIT not being good with interpreter-style patterns in code - so that might slow down things if templating is involved. Regards, Martijn
