[Samba] Old application very slow

Hi,
This weekend I migrated a samba-server to new hardware and software :
I'm running samba 3.2.7-11.3.2 on Opensuse 11.1.
Everything works fine I believe except for an old DOS-application,
written in Clipper. It's too slow to be usable. I tried to debug this
but I'm stuck.
I put the loglevel to 10, but I can't see anything wrong.
I first added to veto oplock files : *.dbf/*.ntx/, no effect.
I didn't have oplocks off, but now I disabled them, with no effect.
I moved all files to another share (from Data to Applic) with no effect.
Am I right that if I wait long enough (few minutes) the modified config
is read without interupting the services ?
I hope someone can point me in the right direction.
Koenraad Lelong.
