Python 2.5 as of last night:

Python 2.4:

<sigh> I put the headings for the timeit.py output on the
wrong blocks. Thanks for pointing this out.
Anyway, try for yourself. Just add these lines to pybench/Call.py
at the end and then run Call.py using Python 2.4 vs. 2.5:
### Test to make Fredrik happy...
if __name__ == '__main__':
 import timeit
 timeit.TestClass = PythonFunctionCalls
 timeit.main(['-s', 'test = TestClass(); test.rounds = 1000',
 'test.test()'])
