nsslapd-db-transaction-batch-val

Specifies how many transactions will be batched before being committed. You can
use this attribute to improve update performance when full transaction durability
is not required. This attribute can be dynamically modified using
further information on modifying this attribute, see Chapter 14, "Tuning Directory
Server Performance" in the Netscape Directory Server Administrator's Guide.
If you do not define this attribute or set it to a value of 0, transaction batching will
be turned off and it will be impossible to make remote modifications to this
attribute via LDAP. However, setting this attribute to a value greater than 0 causes
the server to delay committing transactions until the number of queued
transactions is equal to the attribute value. A value greater than 0 also allows you
to modify this attribute remotely via LDAP. A value of 1 for this attribute allows
you to modify the attribute setting remotely via LDAP, but results in no batching
behaviour. A value of 1 at server startup is therefore useful for maintaining normal
