If anyone has any testing code that others can compile to compare times, I would be willing to do so. I feel tempted to write my own test code, because this is bothering that the windows functions may be that much faster.

I still have to say that I would be very surprised to find out they are. FillYourBrain, are you positive the speed differences could not be attributed to some other factor? I fail to see why the windows OS would not perform the same caching features on the standard functions, as it does with the win32 api functions. Especially after _Elixia_ has stated that, aside from some overhead, they are, in fact, the same calls.
