There could be a real issue here, but for what it's worth I haven't noticed such extreme slowdown. But I don't have a Windows 7 machine to compare to. I upgrade the one I'm on now from Windows 7 to Windows 10 over a year ago, so if there ever was a difference maybe I just got use to it and didn't notice. I don't recall any major issues when I first upgraded either though ¯\_(ツ)_/¯ -- 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
