FWIW, I get
python -m timeit "import inttest; inttest.inttest2(5)" 10 loops, best of 3: 367 msec per loop
\Apps\Python30\python -m timeit "import inttest; inttest.inttest2(5)" 10 loops, best of 3: 810 msec per loop
That's on Windows XP, distributed binaries of Python 2.5 and 3.0a1. Processor speed: 1.7 GHz Processor type: Intel(R) Pentium(R) M processor
That's 120% slower (but against very different versions).
I guess this proves nothing much, apart from the fact that the test is wildly variable and as such probably not very valid :-)
Paul.
