nsslapd-dbcachesize

This performance tuning-related attribute specifies database cache size. 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
additional error information explaining the problem.

NOTE

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
