So I tried it both ways. With 1.5 I set home to be the empty directory /home/smited (under c:/cygwin). It didn't make it any faster. With beta-1.7 I set home to /cygdrive/c/Documents and Settings/smited (where all the cruft is) and it didn't make it any slower. So where cygwin points $HOME at terminal startup does not seem to have an effect for me. Current version 1.5 is slow while beta-1.7 is fast, for still unknown reasons. -- 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
