To: The Cygwin Mailing List Content-Type: text/plain; charset="UTF-8" X-IsSubscribed: yes X-SW-Source: 2019-03/txt/msg00152.txt.bz2 I've recently been having general performance problems on my Win7 laptop, mostly realized by very slow switches to workspaces (Dexpot). I've been watching processes using high cpu, and I'm trying to watch for processes with high i/o, but I'm not as certain how to find those (I'm using Process Explorer). I finally discovered that when I kill my Cygwin Emacs process, it clears up immediately. When I restart Emacs, it's fine for a while, but then it eventually slows down again, and then killing it clears it up again. I've found other processes that are suspicious in terms of performance, but none of those had as much of an impact as the Emacs process. Curiously, when I'm actually USING Emacs, I don't notice any particular slowdown. My Emacs process mostly just sits, without very much foreground activity. I sometimes have pretty large file buffers, in the megabyte range. I vaguely remember recently seeing some messages go by on the list about perf problems with Cygwin Emacs. I didn't read them at the time, as I wasn't having an issue. Cygwin 3.0.1(0.338/5/3); Emacs 26.1. -- 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
