I'm continuing to see this problem. I find that when my system is very sluggish, if I check total IO, those three processes are at the top of the list, and this is when I'm not doing anything directly with Cygwin. At this point, if I kill my Emacs, rxvt, and X server, my performance improves considerably. -- 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
