Guys ...
Been racking my brains out past 3 days till now.
Here's the background:
I have migrated my Old Samba (rhel4) server to the New Samba (rhel5)
server.
Rsynced the data across. NO issue.
New Server, using Old server's smb.conf, smbpasswd, as well as ported over
passwd, group, shadow files.
Hostname , IP, etc has been changed to Old server's settings before SMB
service is started.
Apparently, it works, BUT the access to it, is slow, latency can be felt.
And thru the logs, i initially do see "tdb errors"

Individual log files can be seen with alot of the following:
yield_connection: tdb_delete for name "example: SHAREFOLDER NAME" failed
with error Record does not exist.
Till now those errors are not reflected, but still slow and latency felt.
Not sure, it's anything to do with the TDB files? What will happen if i
chose to stop the SMB service, and remove the TDB files to let it regenerate
a new set?
Any advice is really really appreciated, and thanks in advance =)
With Regards,

1)Are you running the latest version of OS plus Samba on RHEL 5?
2) You do have duplex and speed setting on your NIC card(s) set up properly?
3)Does the 'testparm' SAMBA utility report anything weird with your
smbd.conf file?
4)In terms of the tdb files, have you backed them up during the file
migration? (usually under
/var/lib/samba). Usually I do (see SAMBA HOW TO 41. Managing TDB files.
I am not sure how tdb file lookup could affect performance at large.
