Now that Chandler is runnable with python 2.5 on the branch I did some performance comparisons between trunk and that branch. I was expecting overall improvement of around 10%, but unfortunately it does not appear that way.
The first column shows the test, second column the time (in seconds) with Python 2.4, the third the time with python 2.5, and the last the difference between the two. A negative value in the last column means we got that much faster with 2.5. I run the tests just once, but I had shut down most applications and I wasn't doing anything else with the machine, and this being dual core I would expect the normal variation between test results to be under 2%. In other words, any difference less than +/-2% might not be a real indication of change. The tests were run on Ubuntu Linux (Dapper Drake).
