[Samba] Slow file listing : Debian Wheezy, Samba Version 3.6.6

[Richard]

Hi,

I manage quite a few boxes that are identical in OS and Samba version. 
(Debian Wheezy, Samba version 3.6.6)

I have one box, where each time you open windows explorer and click on 
the mapped network share, a line moves across the top of explorer and it 
takes around 30-40 seconds to display the directory listing.

Once it has done this once, it is quick thereafter, until you close 
explorer and open it again later, then it is slow again.

Can anyone give me some direction on where to search for the cause of 
this issue please ?
