+<para> There are several elements which can nest within
+container-invoker-conf, one of which is <![CDATA[<Optimized>]]>. This
+controls the behavior of bean method calls within the Java VM in which
+jboss is running. If the value of Optimized is "false" then the
+container will behave per the EJB spec and all objects passed into and
+out of bean remote methods will be marshalled over RMI regardless of
+whether the client is running remotely or in the same VM as jboss.</para>
+
+<para> If the value of Optimized is "true" then objects passed between
+bean methods and clients in the jboss java VM will be passed by
+reference rather than by value. This is <emphasis>much</emphasis>
+more efficient (and can result in substantial performance
+improvements) but can result in unexpected behavior. For example, if
+a bean has a member object and returns that object from a get() method
+then the EJB-specified behavior is to make a copy of that object which
+is returned over RMI to the caller. Therefore if the caller modifies
+the returned object in any way she will modify the copy of the object.
+If Optimized is "true" then the caller will modify the original object
+per se, rather than a copy.</para>
