For some reason file operations have become very slow inside emacs starting yesterday. It's especially painful when saving a file that's managed by mercurial (more than 20 seconds!), but I've seen it on the command line as well (x-server takes a similar amount of time to start, for example). I'm running the latest everything and I've run rebaseall. I verified that Windows Defender did not silently re-enable itself since I last disabled it (you can't actually uninstall it) and no other BLODA are present on my machine. The problem persists across reboots.
I have vague memories that this has turned up in the past (maybe 12-15 months ago?) but Google isn't turning up anything. Attaching strace to emacs during the save makes it take a full 35 seconds and reports the following:
$ cat emacs.strace | awk '{if ($1> 1000000) { print }}' | grep -v timer_thread 26910790 26912157 [main] emacs-X11 5188 child_copy: dll bss - hp 0x264 low 0x611FC000, high 0x61230770, res 1 1128419 2125655 [main] python2.6 5188 read: read(5, 0x8009DB60, 65536) blocking 25850184 32830582 [main] python2.6 5188 stat_worker: 0 = (\??\C:\cygwin\cygdrive,0x28BB68)^^^^^^^^^^^^^^^^^^^^^^^ This looks suspicious. I assume you're suffering from SMB network scanning.is there a workaround? Neither "always run elevated" nor "always keep all network drives mounted" seems like a reasonable requirementWhat are you expecting? Was my reply in http://cygwin.com/ml/cygwin/2012-02/msg00375.html not sufficient?
