Here's an interesting blog post comparing Python performance of various versions from 2.2.3 upto the latest 3.0 beta.

The fact that only Mandelbrot calculation (a hardly representative benchmark for a high-level dynamic language such as Python) has become significantly slower is rather a good sign IMO.

This comment makes the whole post fairly farcical though: "I decided to not use pybench, but to take some of the benchmarks from the Computer Language Benchmarks Game instead (hoping they are slightly more "real use" realistic)."

From what I can tell, the main graph is being dominated by the dramatic mandelbrot slowdowns between 2.4 and 2.6, and that is heavy on the complex arithmetic.

The numbers from pybench would have been far more enlightening. Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia --------------------------------------------------------------- http://www.boredomandlaziness.org
