The browse take 6 to 7 seconds (even with the method above). I have 64megs of RAM on a PII.

Interesting note is that if I set a relation between this large table and a parent table and then choose record in the parent table... the child records are displayed instantaneously. This means that relations between tables are implemented are a more fundamental level than a SQL statement. Perhaps I can harness this concept in my query...
