>One more question if you don't mind. Do you know if it's possible to limit VFP threads to one processor at a time on a dual or quad machine?

What I do to sorta force this is have a report server executable running on my webservers. The EXE monitors a table for any requested reports, then executes them. ASP.NET and VFP DLL componets can put report requests into this table. The benefits of this are:
- the system only executes 1 report (or X reports if X report servers are running). This prevents the webserver becoming overwhelmed with several reports at once
- the report server only uses the resources of 1 CPU, leaving the other CPUs free to serve ASP.NET requests

Also, for very long running reports, I compile all or a portion of the data each night at midnight. Reports requests during the day use this precompiled data.
