I was interested to find some discussion of how the performance characteristics compare to PyPy/Unladen Swallow/RPython. Quick googling only found one comparison: http://jaredforsyth.com/blog/2010/jul/21/cpython-vs-pypy-vs-cython/ http://jaredforsyth.com/blog/2010/jul/21/cpython-vs-pypy-vs-... The routines he benchmarked are simple string tokenizing, though, so I'm not really surprised the translated-to-C version came in so much faster.
