lib/db: Use different defaults for larger databases (fixes #5966) (#5967)

Browse Source 
This introduces a better set of defaults for large databases. I've
experimentally determined that it results in much better throughput in a
couple of scenarios with large databases, but I can't give any
guarantees the values are always optimal. They're probably no worse than
the defaults though.
