Not too huge database for VFP in LAN. It seems your application doesn't use indexes enough and pumps entire database along wires. If you will ensure that you doesn't use non-optimized queries/commands and still is not satisfied with the speed - you should think about client/server model. First step can be DCOM, i.e. placing a business object to power machine and using it's methods/properties.
