Here the customer has been providing the hardware according to their
internal standards. Not sure about their using *nix.

We are following these OK, using Delphi. We have some 160+
installations already running OK, with lots of happy users, but none
approaching any limits. This one is a biggy and we have some other big
ones in the horizon.

Our customers use our programs to do proposals based on light number
crunching. So the load on transactions is not that heavy. But the
main database has grown to some 6 Gig. We have two other databases
involved in the program. One is getting big with historical number
crunching data (about 2 Gig) and another smaller one.

I am trying to see what are the practical limits for concurrent users
for SS and Classic if we have 8 processors and 3.5 Gig of RAM. Then
based on that, we can see if we need to do something else to support
this client.
