The 11 arg will tell you if FoxPro is using indexes when the tables are joined (avoid "cartesian joins"). On a couple views I was able to improved view speed by two orders of magnitude by simply re-arranging the order of tables in the FROM ... JOIN clause.


This may have helped a bit, but even when the joins were optimized, or there were no joins, the SQL's were still too slow.
