Realizing that early releases don't normally perform as well as final releases, I ran pystone for 2.5a1 and compared with 2.4.2 (what I had handy). 2.5a1 got slightly more than 30k, while 2.4.2 gets slightly more than 35k (1.4 GHz, Pentium M, 1 Meg L2 cache).

We should verify that all the compiler optimizations that existed in Python 2.4 still exist in Python 2.5. We didn't expend much effort in that area during the compiler development. Not sure if there are any that would affect pystone or not.

I also ran a large test suite for a project with both 2.5a1 and 2.4.2 and got nearly identical times. I haven't seen general performance mentioned here lately, so I thought I'd share those numbers. On a related note: it might be nice to put a pystone run in the buildbot so it'd be easier to compare pystones across different releases, different architectures, and between particular changes to the code. (That's assuming that the machines are otherwise idle, though.) -- Benji York
