I did all tests below in emacs -Q. //gbgfs1/archive75 is a share that contains 260 directories and three files. The server is located in our office. C-x d //gbgfs1/archive75 RET Emacs 22.1.1: 1 s Emacs 23.0.95.1: 95 s So, that is about 95 times slower... Opening a subfolder in dired in the directory listing I got in the above operation. The subfolder opened contains only one folder.

My PC has a Pentium 4 CPU, running at 3 GHz, with 1.5 GBG of RAM, according to My Computer -> RMB -> Properties -> General and I am using Windows XP Professional, Version 2002, Service Pack 2. Any tests in particular you want me to run? /Mathias
