samba - Jun 2005 - Slow Ms Access in one share

Hi,
I have samba-3.0.11-1 on a Red hat ES 2.1 box.
I also have a Win 2003 Server Domain Controller, to which my users should
autenticate.
My files are all in linux machine (+ also apache, mysql etc)
I have also an Access mdb that could be open by several user at same time,
based on linked mysql tables.
Opening certain masks in access is veryyyyyy slow, so I try to create
another share, accessible from everyone, and put there the same db. Well,
this way Access works fast.
I'd like to know which is the reason for the performance difference.

Here my samba conf
Thanks

Why do you have oplocks turned off? You'll find that Access goes a  
lot faster when you leave oplocks on. That, or at least reduce the  
"lock spin time" from 200ms to something less (eg: 20ms), or remove  
that parameter to let Samba use the default.
