Admittedly, this place has a sub-optimal network setup; the Samba box and DB
server are plugged into one switch, which has the uplink port from another
switch plugged into it. This second switch has workstations plugged into it
and a cable running from (you guessed it) the uplink port of yet another
switch that services workstations - all connections are 100 Mb.

There is a DB server in place, which is one reason I'd prefer to keep the
network traffic low as to not tie the DB server up waiting to send result
sets down the wire. The app does a lot of processing on both the client and
server side, and neither side massively efficient (hint: the DB server and
client-side libraries both come from www.guptaworldwide.com).

Sounds like an excellent testimonial to hit clients with that are
considering going with some weird MS server product....
