All components should be tested with the both behaviour client and server state saving method.

When the save_state_method is set to the server side all requests are faster than the client side.
Mapfaces components should be implemented for server and client behaviour.

note: to change the save state method
go to youe web.xml and add the following tag

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>
