<h2 id="rzahyservercaches">Server caches</h2>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>The following sections discuss each of the LDAP caches and demonstrate
|
||
|
|
how to determine and set the best cache settings for your system.</p>
