You expect too much, it is Windows under the hood and no one but
Microsoft can change that performance issue.  Windows alone (meaning
without Cygwin) is orders of magnitude slower than Linux.  Cygwin adds
another layer of slowness just because of the emulation required.  You
might get a tweak or two of milliseconds by modifying some underlying
code but you're not going to get too much more.
