Any cd command on local hard disk drive slows extremely down when I connect another drive letter to a network drive. Look at how I took the time: Example 1: Drive Q: is connected to a network drive, connection is via a slow VPN mobile phone (GPRS) line. All the example below is only on local hard disk drive C:\. The slow drive Q: is not involved, but it's presence slows down any cd command on local drive C:. My $PATH does involve ".", some paths on C:, but nothing on Q:. Shell is tcsh. The cd command on the local drive C: takes 5.8 seconds (!) to complete: /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>mkdir x /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>l drwxr-xr-x+ 1 Test2 mkgroup 0 05.02.2011 20.39 x/ /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>time cd x 0.015u 0.046s 0:05.80 0.8% 0+0k 0+0io 1203pf+0w Example 2: Same situation, but now Q: is disconnected. The cd command on the local drive C: now completes in 0.01 seconds: /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>mkdir x /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>l drwxr-xr-x+ 1 Test2 mkgroup 0 06.02.2011 00.16 x/ /cygdrive/c/Dokumente und Einstellungen/Test2/Desktop/cy>time cd x 0.015u 0.000s 0:00.01 100.0% 0+0k 0+0io 1253pf+0w I am running cygwin-1.7.7-1 (downloaded 2010-11-02) on a Windows XP SP 3. Does anybody have an advice?
