We're getting ready to do a major upgrade here (from NT 4.0 Server to 2000 Server and Win 95 Clients to XP Prof. clients).

We, of course, use a VFP app that requires a lot of data entry/retrieval throughout the day - as always - speed is essential. The app resides on the client while the data is on the server. We're not using SQL server - just plain old VFP. We're approaching 1 GB of data (861 MB to be exact).

It would be great if some of you would offer suggestions as to how our network should be setup to acheive the best performance possible. Things like:

How much benefit will we see (from VFP) with a two-processor server compared to a single processor?
How much RAM in the server?
Would a seperate machine that would share the VFP data provide any benefit?
Most of the activity is on the third floor, would placing an additional server there help?
If we could have a seperate server to handle MS Exchange - would that help?

Any other ideas would be appreciated. Thanks for your help!
