BDB transactions require some extra overhead and work on the part of
the programs using the database, extra overhead when modifying the
database, as well as extra locking before the BDB environment is set
up to ensure that the database crash recovery stuff is done correctly.
I'm not sure BDB would acquire any benefit from their use.
