Thank you for your help Antonio. It seems a little indentation problem in the modified arp.py file you attached makes the main() loop to return after a single packet. I attached the updated version.
ops, I should have taken more care: actually, I was a bit surprised to see such a huge improvement, but didn't check more. This is what happens when you don't have tests to run ;-)
The actual new figures are: CPython: ~580ms (~310ms with initial version) PyPy: ~1120ms (~1300ms with initial version) So, the manual cast of array to c_void_p makes the program around 2x slower on CPython, and only marginally faster on PyPy. PyPy spends now most its time in pointer.py:_cast_addr().
uhm, indeed, then my suggestion doesn't work very well. I suppose that I should just add support for arrays to the fast path. ciao, Anto _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
