Thanks. No smoking gun in sight there. But out of curiosity, can you
do a test run with *no* indexes on the table, just to see if it behaves
any differently? Basically I was wondering if index overhead might be
part of the problem.
Also, the X-axis on your graphs seems to be total number of rows
inserted ... can you relate that to elapsed real time for us?
