FYI, there's a recent thread up on the pypy ML where someone is complaining 
about PyPy being substantially slower than CPython when running Django on 
top of SQLite. Also note that PyPy doesn't implement Py3 yet, so the 
benchmark results are not comparable anyway.

As usual, benchmark results depend on what you do in your benchmarks.
