PyPy outperforming CPython and Psyco

David Ripton ran a bunch of implementations against his collection of Euler Challenge solutions:

And now PyPy is clearly the fastest Python implementation for this code, with both the most wins and the lowest overall time.  Psyco is still pretty close.  Both are a bit more than twice as fast as CPython.

I’d really like to see memory usage for these tests, too.
