I stopped cygserver I ran your commands to recreate /etc/passwd and /etc/group (they now contain 1 line and 3 lines respectively - before it had about 10 & 21 lines in each) To create a bash terminal window (from cmd) takes about 5-6 minutes. cmd /v:on /c "echo !TIME! & C:\cygwin64\bin\mintty.exe /bin/echo "test" & echo !TIME!" 11:01:20.27 11:06:59.78 = 5:39.51 Starting cygserver: 11:08:31.55 11:08:31.62 = 0:00.07 Stopping it again: 11:09:19.02 11:15:04.45 = 05:45.43 With the 'db' entry excluded as a control: 11:15:56.80 11:15:56.90 = 00:00.10 I reverted back to use files+db and my larger passwd and group files, turned on cygserver: 11:19:34.31 11:19:34.38 = 00:00.07 Regards Dennis -- 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
