A DB_CONFIG file can control how much of the database is cached in
memory and on disk.  It gives you other tunables as well, many of which
I'm not familiar with.  If you use OpenLDAP with a BDB backend, for
example, you *must* have one of these files to control your LDAP
server's performance.  See recommended OpenLDAP settings at
http://www.stanford.edu/services/directory/openldap/configuration/bdb-config.html
