I recommend you to confirm your system setup first. Assuming that you 
are experimenting on a reasonably up-to-date platform, more than 6 days 
for adding 2 million entries seems too much even without the BDB 
scalability patch. When I compare your numbers with my results, your 
configuration is 6.6x slower than mine originally (before applying BDB 
scalability patch). Fair comparison could follow after first bring the 
baseline performance in sync.
