Can you provide any more detail about the algorithm and the number
of rows that you might have to insert or update? How did the test
triggers work? If you used row-level triggers and if a trigger on
one row updated multiple rows, then you might have been updating
rows more times than necessary (once by explicit update and one or
more unnecessary times by triggers on other rows).
