Thorough Python 2.7.3 Windows Build Documentation?

Hello fellow Python programmers,

I'm building a 32-bit CPython 2.7.3 distro for Windows using the MS Visual Studio Professional 2008 SP1 (and all hotfixes) MSVC 9 compiler.  My build works, technically, but it also happens to benchmark over 30% slower than the precompiled binaries in the distributed Python 2.7.3 MSI.  Can anyone point me in the direction of some thoroughly detailed build documentation so that I can figure out how to get that 30% back with my build?  The only documentation that I can find just says MSVC 9, period.  There's no mention of SP1 or not, hotfixes, nor of any specific compiler/linker optimizations used to build the official distro.  Something, somewhere, has to be significantly different between our builds for a 30% performance difference, and it'd probably be handy for the Python community to know how to avoid the same pitfall that cost me performance so that we can all get the most out of Python.  Any and all help will be greatly appreciated.  Thanks.

Sincerely,
Arah Leonard
