Me too, I've already proven back in 2008, that out of the box
compilation with VS2008 is not faster.

VC6 with sh scripts (on top of cygwin I believe)

The new version fot he CRT is not that is faster or slower, it offer
"safer" CRt functions for string processing and other stuff, the CRT
speed should not be the impact here.

Of course: code optimization is crucial in the CRT, but is not eh bottleneck.
