Py 2.5 on Language Shootout

[bearophileHUGS at lycos.com]

The The Computer Language Shootout has just published results for
Python 2.5 and Psyco 1.5.2. Comparing the old (Python 2.4) Gentoo
Pentium 4 results (now not visible anymore) with the new results, I
have seen that all the tests with Python 2.5 are faster than the ones
with Python 2.4 (some results can't be compared because N is changed):

Gentoo Pentium 4, Python 2.4.3 measurements:

Regarding Psyco, two tests only are worse (the sourcecode, CPU and SO
are the same):

Old (Python 2.4.3, older Psyco):
nsieve	4.22	22,680	211	 9
reverse-complement	1.66	49,336	330	 2,500,000

New (Python 2.5, Psyco 1.5.2):
nsieve	4.26	22,904	211	 9
reverse-complement	1.75	52,056	330	 2,500,000
