It used to be that you could tune some Samba configuration file
(smb.conf) parameters to get better performance, but AFAIK, all
those are now the defaults.  The important thing is to not mess
with them.

If there are any exceptions to this, I'd sure like to know about
them!  You can look through the manual page for smb.conf(5) and
see if anything applies to your network and might conceivably
gain some performance.  Try searching the manual page for
"performance": this will get you off to a good start.

Also, you can check the first edition of Using Samba for the
appendix on Samba Performance Tuning (I think it was Appendix A).
http://samba.he.net, or look in the docs/ directory in the
Samba source distribution.

Aside from that, it seems that nowadays the issue is more about
getting your network hardware working right, the network configuration
on the Unix host system, and the performance level of the system you
are running Samba on.
