>I have a table created by Foxpro 2.5 DOS containing about 620,000 records residing on a WinNT Server. If I run a very simple (rushmore optimizable) query using FoxPro 2.5 DOS, the time is 2.87 seconds.

Hi Chris,

I had the same problem in the past. The only solution is to create correct index files to speed up queries. Don't forget create index with expression: Deleted() and any name. After I tuned up indexes, VFP began execute queries much faster than FoxPro for DOS.
