The pybench results match those of timeit.py on my test machine in both cases. I just mixed up the headers when I wrote the email. Here's the console print-out: Tools/pybench> ~/projects/Python/Installation/bin/python Calls.py 10 loops, best of 3: 21.8 msec per loop Tools/pybench> ~/projects/Python/Installation/bin/python Exceptions.py 100 loops, best of 3: 15.4 msec per loop Tools/pybench> ~/projects/Python/Installation/bin/python Python 2.5a2 (trunk, Jun 8 2006, 01:51:06) [GCC 3.3.4 (pre 3.3.5 20040809)] on linux2 Tools/pybench> python Calls.py 100 loops, best of 3: 18.2 msec per loop Tools/pybench> python Exceptions.py 100 loops, best of 3: 17 msec per loop Tools/pybench> python Python 2.4.2 (#1, Oct 1 2005, 15:24:35) [GCC 3.3.4 (pre 3.3.5 20040809)] on linux2 Calls.py is using timit.py against the PythonFunctionCalls test and Exceptions.py the TryRaiseExcept test. Function calls are slower in 2.5, while try-except in 2.5 is faster than 2.4.
