Try:

INDEX ON DELETED() TAG DELETED

and see if you see any improvement, running the query from the file server. An article was published some time ago in FoxPro Advisor that talked about the advantages and disadvantages of indexing on DELETED() for Rushmore optimization.

You can create a VFP DCOM server (.exe) that runs on the server and can be called from workstations running your application. Since the DCOM server runs on the same server as the VFP data, access is very fast. The DCOM server can send the results of the query to a temporary table, which the client application can then access.
