Cygwin 1.3.11 DLL Slowness After 6/10/2002


All cygwin operations have a significant delay on my system (Win2K-SP2) 
when using any of the snapshots after 6/10, including the current test 
1.3.11 release distributed with setup.  Reverting back to the 1.3.10 
release or even the 6/10 snapshot immediately corrects the problem.  

For example, opening a bash prompt (i.e. using cygwin.bat in a Win2K 
command shell), which normally takes only 3-4 seconds, now takes from 
15-30 seconds (up to 10 times longer than before).  Nothing else has 
changed on my system other than the cygwin DLL version.

Here is the output of the time command with different DLL versions:

bash-2.05a$ time uname -srvm

bash-2.05a$ time uname -srvm
CYGWIN_NT-5.0 1.3.11s(0.53/3/2) 20020621 01:37:56 i686

real    0m2.975s
user    0m0.030s
sys     0m0.030s

As you can see, the time increases significantly as of the 6/14 snapshot, 
then decreases by almost half on 6/16, but it is still almost ten times 
longer than with the 6/10 snapshot and the current release.

Let me know if it would be helpful for me to run additional tests, etc. 
to narrow down the source of the problem.
