[Samba] Extremely slow during browsing some directories

[Linwei Cheng]

hi,

I am quite new on using Samba and sorry maybe ask a silly question here. I 
set up simple Samba server on Fedora3 using the samba rpm package comes with 
fedora3( version 3.0.10-1.fc3). I use the SHARE security level to make 
things easier. Everything goes fine so far, except that for some windows 
user, some times, on browsing some directories, it takes extremely long time 
to display the folders/files list. This seems weird because it happened 
radomly: sometimes for the same user, same machine and browse same 
directory, it works quickly, but sometimes it take about a minute to get the 
response from server. What's the possibilities for this issue? Deperately 
need help.

My /etc/smb.conf :

[global]

# workgroup = NT-Domain-Name or Workgroup-Name

workgroup = geophysics

# server string is the equivalent of the NT Description field

server string = fileserver

netbios name = fileserver
