+<title>Performance and Cacheing</title>
+<p>Some users of DBD authentication in HTTPD 2.2 have reported that it
+imposes a problematic load on the database. This is most likely where
+an HTML page contains hundreds of objects (e.g. images, scripts, etc)
+each of which requires authentication. Users affected (or concerned)
+by this kind of problem should use <module>mod_authn_socache</module>
+to cache credentials and take most of the load off the database.</p>
