LDAP caches are fast storage buffers in memory used to store LDAP information such as queries, answers, and user authentication for future use. Tuning the LDAP caches is crucial to improving performance.
An LDAP search that accesses the LDAP cache can be faster than one that requires a connection to DB2, even if the information is cached in DB2. For this reason, tuning LDAP caches can improve performance by avoiding calls to the database. The LDAP caches are especially useful for applications that frequently retrieve repeated cached information.
The following sections discuss each of the LDAP caches and demonstrate how to determine and set the best cache settings for your system.
For information on configuring caches, see Adjust performance settings.
