[Samba] oplock_break problem

It is possible to turn off oplocks ( and level 2 oplocks ) to prevent this 

We found that performance degraded so severely that we needed to turn 
oplocks back on.

To turn off oplocks for all of your samba shares, add the following 
parameters to your [global] settings in smb.conf

level2 oplocks = no

I assume there is a lot of development going on in this area for the next 
version of samba, but I don't know for sure.

Good luck,
