(Assuming indexes work as intended) the major performance factor,
especially in the case of sqlite3 data source, is the number of SQL
queries needed to resolve a single DNS query, rather than the size of
the DB.  So, depending on the configuration this result is not
necessarily surprising.  In general, answers that contain more RRs
would take more time.
