just out of curiosity i've downloaded the latest Version of Psyco V2 Beta 2 and run the benchmarks against the old Version of psyco 1.6
Because it might be of common interest, i am posting the results here. My machine is a Pentium D 3.2 Ghz running Windows XP SP 3 and Python 2.6.2. Psyco V2 was built with 4.3.3-tdm-1 mingw32 with optimisation flags changed to -O3 Benchmark | avg.
