I'm disappointed in Cygwin's slowness too. Corinna and I have spent many hours pouring over MSDN, internals books, and internals web sites. I've spent time looking at ReactOS sources trying to see if they would provide any insight into how Windows does things. It's possible, maybe even likely, that there are things that could be done to speed up Cygwin but I don't think it's likely that they include using simple Windows API stuff like the suggested GetFileAttributes() or limiting Cygwin's POSIXness. And, if speed ups do exist, they definitely do not require a private audience with me or Corinna. The best place to discuss improvements is actually the cygwin-developers mailing list. And, as I said, if you do have a patch to propose, it would pay to start early on getting the paperwork done. cgf -- 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
