We did not assume it would be slow either.  However, at some point we 
made the change in
cmake because we found that much of the run time on windows was spent in 
stat, and that linux
stat times were a much smaller part of the run time.  I do not remember 
the exact numbers, but
I do remember it being a significant speed up, 2 to 3 times faster.   I 
will see if I can create a test
case that uses both.  The only thing I can figure is that the stat call 
may do some sort of memory allocation
and copy to get from the native windows structures to the POSIX's 
structure.
