I am on vacation (really) so I probably will not respond to any
reply to my below comments until July 10th.

Jeff, just to make sure I understand what is being said I'd like to
repeat what you are saying. In short the data upload from the
mtt client and the php script is done one test case at a time.
However, the bulk of a test run (a group of test cases) is written
as one table at some single point in time (when the run is done).

Is there no way for us to add rows to an existing table using perfbase?
