Have you made some benchmarks like pystone?
Its seems to me version 2.6.1 is not optimized build so I remove(uninstall) it.
I repeat the pystone tests with an optimized GCC(mingw32) build.

python-2.6-MSVC -- shell=cmd.exe 35891,3; 35827,9; 35791,3; 35901,7; 35876,5; 36081,1; 36149,2 average=35931,3 deviation=132,7 -- shell=bash.exe(msys) 35532,9; 35621,1; 35526,8; 35639,4; 35671,2; 35702,4; 35633,0; average=35618,1 deviation=66,1
I don't have idea why performance of official python 2.6 goes down(see previous results below). It is same PC. Every tested program load own files.
The result show unexpected behaviour:
- the MSVC build is faster by ~0.9% if it is run under cmd.exe then msys bash;
- the GCC build is faster by ~0.9% if it is run under msys bash.
Otherwise results lock similar but note that builds use different source base and in this case we may can't compare.
The old results:
There is result from pystone test test run an old PC (NT 5.1): - 2.6(official build): 42194,6; 42302,4; 41990,8; 42658,0; 42660,6; 42770,1 average=42429,4 deviation=311,6 - 2.6.1(official build): 35612,1; 35778,8; 35666,7; 35697,9; 35514,9; 35654,0 average=35654,1 deviation=88,1 - trunk(my mingw based build): 35256,7; 35272,5; 35247,2; 35270,7; 35225,6; 35233,5 average=35251,0 deviation=19,2
There is problem with python performance between 2.6 and 2.6.1 ~ 19% :(. Also the test for GCC-mingw is not with same source base. Roumen
