6	6	* Install and configure [[JavaMelody>>http://code.google.com/p/javamelody/]]
7		-* [[Use a Profiler>>http://dev.xwiki.org/xwiki/bin/view/Community/Profiling]]. This has the advantage of providing advanced information, but has the drawback of being resource intensive and thus slowing the XWiki instance. It also requires a special startupscript.

	60	+XWiki can use different cache implementations. The JBoss Cache and JBoss Infinispan implementations have nice JMX features available as shown below.

	62	+Since XWiki 3.3 the default implementation is JBoss Infinispan.
