Here's the numbers. It looks like something changed between python 2.2 and 2.3 that made calling PyEval_InitThreads a lot less expensive. So, it doesn't seem to make a whole lot of difference on recent versions of Python.
Thanks. I see similar results for 2.3 and 2.4 on OS X (don't have 2.2 here).
It's very much a guess, but could this patch:
[ 525532 ] Add support for POSIX semaphores
be the one to thank?
No, Mac OS X doesn't implement POSIX semaphores.
Well, does OS X show the same effect between 2.2 and 2.3? I don't have a 2.2 on OS X any more, I was just talking about James' results on linux.
I don't have 2.2 on OS X any more, either. -bob
