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.
