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. -- Earnie -- https://sites.google.com/site/earnieboyd -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
