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.

 Emacs 22.1.1: immediate (under 1 s)
 Emacs 23.0.95.1: 3 s

Opening a file, 2470 bytes, using RET in dired and in a directory
further down in the structure above:

 Emacs 22.1.1: immediate (under 1 s)
 Emacs 23.0.95.1: 3 s

I opened a file that was about 20 times larger than the above, from
the same folder, and it took about the same time, so it seems that the
actual reading of the file contents is not affected.

Opening a folder with about 270 files even further down in the same structure:

 Emacs 22.1.1: 2-3 s
 Emacs 23.0.95.1: 86 s

This seems to happen for any type of file I open.

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?
