Hi Theodor, Question: last cygwin 2.0.4 or previous version ? Maybe is no relevant for your case but there were some fixes In theory during tests a 64K buffer should be faster Regards Marco -- 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
