Freebsd 5.4+samba

[Monah Baki]

Hi all,

I just installed Freebsd 5.4 with samba 3.x, I'm running a calyx  
software, and the 6 clients are winxp.
The smb.conf is as simple as possible. I noticed that some clients  
are very slow to connect to the share drive and run a database search.
The server is a dell 8400 optiplex, no scsi HDD (sata I think), 3Ghz  
and 512MB Ram.
I was wandering if there's a way to optimize samba, or freebsd. Right  
now performance wise is worse then when they connect to the same  
database on a win2003 server and I need to get the win2003 server out  
of the picture.


Thank you
