From: Bryan Berns To: cygwin@cygwin.com Content-Type: text/plain; charset=UTF-8 X-IsSubscribed: yes X-SW-Source: 2015-04/txt/msg00285.txt.bz2 Based on some rudimentary performance tests, it would appear that Cygwin may repeatedly try to lookup information on a SID form an ACE if cannot find a corresponding account.... which will undoubtedly occur for orphaned SIDs. If the volume being read is remote, this can result in some massive slowdowns if there are many files in the directory. Is there any way to augment this behavior? -- 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
