Some more interesting results from comparing Python 2.4 (other) against the current SVN snapshot (this):

Here's the list again, this time without wrapping (sigh):

The NFS sprint results are also visible. A little disturbing is the slow-down for Python function calls and the built-in method lookup. Did anything change in these parts of the interpreter ?

This is the machine I used for running the pybench: Timer: time.time Machine Details: Platform ID: Linux-2.6.8-24.19-default-x8664-with-SuSE-9.2-x86-64 Processor: x8664
