RMI-IIOP. We have around 100-ish clients connected to the server,
people creating orders, adding items to orders, people printing
orders, picking orders, verifying each line item on the order, making
POs, etc...I don't really know how many connections, but I'd say lots.
As for data, some people are retreiving info about a single product,
anywhere from just name, price, qty in stock, to retreiving past POs
that ordered thousands and thousands of parts.

Some simple searches, such as retreive the product with a give product
number responding instantly on windows and sometimes being almost as
fast to taking 5 seconds.   Browsing purchase orders by vendor can
take a few seconds to retreive a list of vendors, where it's
instantaneous on windows.

Dual Intel Xeons, actually.

I think not.
