The fix is to make sure your CYGWIN environment variable contains tty before starting the console. I use a modified Cygwin.bat that does this.

hi, I have simplified the test case a bit. Wrote 2 .py files, one I get
slow emacs, the other I get normal(smooth) emacs:
$cat slow.py
#!/bin/python
import os
os.close(0)
os.close(1)
os.close(2)
#must make sure X server is running already, or else this doesn't show
#anything, even no -nw version of emacs. my /bin/emacs is alternative to
#/usr/bin/emacs-X11
os.system("emacs -q")
$cat fast.py
#!/bin/python
import os
os.system("emacs -q")
(And my original problem is `run emacs' in cygwin.bat console will cause
emacs slow, and I observed there's only one fd (socket to X) open for
the emacs process started this way; no stdin/out/err).

The following is the reply I wrote to your request. Luckily Gmail saved it in Sent Mail. Here it is, without the attachment: Sorry. Cygwin is 1.7, I update very often, and I can reproduce it both at home and in office. Here's the steps to reproduce it: 0. Start X, and set DISPLAY: $startxwin.sh $export DISPLAY=:0 1. start bash from cygwin.bat: $cygstart /Cygwin.bat 2. In the cygwin.bat console window, start emacs-X11 using run.exe: $run emacs-X11.exe -q 3. In the emacs window, move cursor up/down, take a note it's speed, and run: $ps aux|grep emacs $ls -l /proc/3804/fd/ #3804 is the emacs pid Here's the output: lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 0 -> socket:[1584]= a2. Quit emacs, start it again in cygwin.bat window, this time use: $emacs-X11.exe -q #without the `run' a3. In the emacs window, move cursor up/down, I can see it's smoother this time. It's reproducible on my PCs both at home/office. And the fd list: lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 0 -> /dev/console lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 1 -> /dev/console lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 2 -> /dev/console lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 3 -> socket:[1612]= Also, I used Procmon to see how emacs is doing. Emacs is sending/recving lots of TCP packets to localhost 1053 (X server I guess), but in the 1st case, 552/861 of their sizes are 32 bytes, while on the 2nd case, 318 out of 723 packets are of size 32. Also, I checked how many of the packets are of size [100, 1000), the result is more illustrative, in the 1st case, 86/861, in the second case, 281/723 The Procmon result with only TCP data is attached, after unpack, there is a slow.csv and a fast.csv. -- 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
