Another issue with the paper:

This is just plain untrue. The first comparison Oracle show has 
BerkeleyDB 7% faster, way short of a factor of three.

Of the *eight* comparisons of Derby to BerkeleyDB (excluding ones with 
Hibernate), *six* seem to have have BerkeleyDB faster by a factor *less* 
than 3. That's a long way from *every* test being between a factor of 3 
to 10.
