Within an acceptable statistical variation in the benchmark tool itself my PGO build performed identically to my regular build. Which means that I'm still running 30% slower than the precompiled binaries somehow even though I'm theoretically using the right compiler. And which also means that I can neither confirm nor deny if the released precompiled binaries are PGO builds or not.


    I remember that some versions of Visual Studio silently completed the PGO build
    without actually having PGO capabilities. :)

    I think for VS 2008 at least "Professional" is needed, for VS 2010 "Ultimate".
