Hi
Does every database consist of a separate b-tree or is "database" just a name spacing convince? I.e. are reads faster for many smaller databases rather than one large database?
As the documentation says, named databases are separate b-trees. Reads may be slightly faster, sure, but not by much. You need to have enough separate DBs to reduce the overall tree height of the equivalent combined tree to see a measurable difference.
