Hi, it would be interesting to see whether it ran faster on IronPython which
compiles Python code to a .NET backend. Apparently the CLR backend can
actually speed up execution times too.

Well, sure. I'd be interested in knowing that. But I don't have access to a .NET environment (don't run Windows, on principle; haven't installed Mono because of a lack of a compelling reason).

If someone with .NET wants to try my hashcash.py module on IronPython, I'd love to see results. Just run:

     ./hashcash.py -sm someone@xxxxxxxxxxxxxxxx

To get some rough benchmarks. The time for generating a megahash varies wildly, but the hashes per second seems stable across runs on the same machine. If you use a machine with Psyco installed (JIT for Python, basically), it boosts it another 20% or so.

In any case, it's a lot slower than the C version. It's even more slower than the *amazingly* good G4/Altivec version, which just screams on my Powerbook (exactly the same as the published benchmark, FWIW)... I guess a G5 is even better.
