Huh ? They do show the speedups you achieved at the sprint.

More or less the same results:
Python 2.4:
Tools/pybench> python Calls.py
100000 loops, best of 3: 18.9 usec per loop
Tools/pybench> python Calls.py
100000 loops, best of 3: 18.8 usec per loop
Tools/pybench> python Calls.py
100000 loops, best of 3: 18.7 usec per loop
Python 2.5 (trunk as-of 2006-06-08):
Tools/pybench> ~/projects/Python/Installation/bin/python Calls.py
10000 loops, best of 3: 22.9 usec per loop
Tools/pybench> ~/projects/Python/Installation/bin/python Calls.py
10000 loops, best of 3: 23.7 usec per loop
Tools/pybench> ~/projects/Python/Installation/bin/python Calls.py
10000 loops, best of 3: 23.4 usec per loop
I've attached the modified Call.py below so that you can
run it as well.
All this on AMD64, Linux2.6, gcc3.3.
