We are trying to troubleshoot slow performance.
A lot of my NT client log files show messages like this about oplock
break issues.

Here is my conf global settings & the share that we turned level2 locks
on..(It is all exe, dll, lib files)
# file name: /etc/opt/samba/smb.conf.DEV
# Samba config file created using SWAT
# from localhost (127.0.0.1)
# Date: 2001/01/02 11:36:07
# Global parameters
[global]

netbios name = SCSSD3
server string = Samba Server

bind interfaces only = Yes

password server = scssd3
log file = /var/opt/samba/log.%m
max log size = 1000

dos filetime resolution = Yes
socket options = TCP_NODELAY IPTOS_THROUGHPUT

oplocks = no
level2 oplocks = no
[t5amprt4s]
path = /t5amprt4/client
writeable = yes
force user = cssuser
oplocks = yes
level2 oplocks = yes
Are there other settings that I should look at adding ?
We've taken care of all dns reverse lookup issues that we've seen.
I don't understand the locking very well to know what to tune.
Thanks for your help.
