Tests done on a 32-bit Linux installation on an Athlon 3600+ X2. Compiled with
gcc in UCS2 mode.
pystone
-------
- 2.5: 43859.6 pystones/second
- 2.6: 42016.8 pystones/second
- 3.0: 38759.7 pystones/second
richards.py

(roughly, richards is an object-oriented method-calling benchmark)
- 2.5: 770.54 ms per iteration
- 2.6: 572.84 ms per iteration
- 3.0: 566.69 ms per iteration
stringbench
-----------

- 2.6: unicode: 256.22 s / bytes: 184.45 s
- 3.0: unicode: 248.07 s / bytes: not tested
