- Try creating table without OIDs  and repeat runs
- Try changing number of inserts per transactions.

I tried similar test on my home machine last week. It gave me 500K records in
about 54 seconds on 7.3.3. That translates to roughly 3 minutes for 1.4M
records. You sure something isn't right here?

What is the hardware? Can you try it with 7.4CVS?
