[Samba] Slow Directory listing

[Yves Lejeune]

When you move the mouse pointer over a file in the explorer, it tries to
prepare to display the information popup.
This means reading a part of the file, even if it is on a network drive.
Maybe there is something similar for directories, even though no information
popup is ever opened.
So you might try to disable the explorer option about information popups.

In case you want to understand what is going on, you could use a spyware,
such as the free utility "filemon" from Sysinternals.
I can show you which files or directories are opened by the explorer.
