Hello there.
I just got round to do some comparative runs of 2.5 32 bit Release, built with visual studio 2003 and 2005.
Here the figures (pybench with default arguments)
.NET 2003:

This is an improvement of another 3.5 %.
In all, we have a performance increase of more than 10%.
Granted, this is from a single set of runs, but I think we should start considering to make PCBuild8 a "supported" build.
Cheers,
