[Samba] 2.2.5 performanc issues...

[Dunville, Barbara]

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]
   security = server
        workgroup = AMEREN
        netbios name = SCSSD3
        server string = Samba Server
        interfaces = 10.81.1.44/255.0.0.0
        bind interfaces only = Yes
        encrypt passwords = yes
        password server = scssd3
        log file = /var/opt/samba/log.%m
        max log size = 1000
        name resolve order = hosts wins
        local master = No
        wins server = 10.101.1.32
        read only = No
        preserve case = yes
        short preserve case = No
        dos filetime resolution = Yes
        socket options = TCP_NODELAY IPTOS_THROUGHPUT
        syslog = 0
        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.
