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

the results you just posted appear to show a 20% slowdown for function calls, and a 10% speedup for exceptions.

both things were optimized at the sprint, and the improvements were confirmed on several machines. on my machine, using timeit on the test bodies, I get noticeable speedups for both tests; from my earlier post:

function calls:

25 usec per loop for Python 2.4.3 22.5 usec per loop for Python 2.5 trunk

try/except:

15.1 usec per loop for Python 2.4.3 23.5 usec per loop for Python 2.5 alpha 2 11.6 usec per loop for Python 2.5 trunk

maybe the function call issue is an AMD64 thing? or a compiler thing? do you see the same result on other hardware?
