For a comparative real world benchmark I tested Martin von Loewis' django port (there are not that many meaningful Python 3 real world benchmarks) and got a speedup of 1.3 (without IIS). This is reasonably well, US got a speedup of 1.35 on this benchmark. I just checked that pypy-c-latest on 64 bit reports 1.5 (the pypy-c-jit-latest figures seem to be not working currently or really fast...), but I cannot tell directly how that relates to speedups (it just says "less is better" and I did not quickly find an explanation). PyPy is ~12x faster on the django benchmark FYI

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.
