I don't know about native Windows speed, but comparing NutCracker with
Cygwin on a simple 'find . | wc -l' already gives a clue that looking
at Cygwin to benchmark NT file inspection IO will give a skewed
picture:

##### NutCracker
$ time find . | wc -l

real    0m 1.44s
user    0m 0.45s
sys     0m 0.98s
  25794

##### Cygwin
$ time c:\\cygwin\\bin\\find . | wc -l

real    0m 6.72s
user    0m 1.09s
sys     0m 5.59s
  25794

##### CMD.EXE + DIR /S
C:\PROJECT> c:\cygwin\bin\time cmd /c dir /s >NUL

##### Cygwin 'find -ls' (NutCracker doesn't have a '-ls')
C:\PROJECT> c:\cygwin\bin\time c:\cygwin\bin\find -ls | wc -l
