nsslapd-dbcachesize

This performance tuning related attribute specifies database cache size. Note that
this is neither the index cache nor the entry cache. If you activate automatic cache
resizing, you override this attribute, by replacing these values with its own
guessed values at a later stage of the server startup.
If you attempt to set a value that is not a number or is too big for a 32-bit signed
integer you will receive an LDAP_UNWILLING_TO_PERFORM error message
with additional error information explaining the problem.

nsslapd-db-checkpoint-interval

The amount of time in seconds after which the Directory Server sends a checkpoint
entry to the database transaction log. The database transaction log contains a
sequential listing of all recent database operations and is used for database
recovery only. A checkpoint entry indicates which database operations have been
physically written to the directory database. The checkpoint entries are used to
determine where in the database transaction log to begin recovery after a system
failure. The

memory-mapped files from crossing quadrant boundaries.
