Reduce default number of view in JSF

By default the number of views/sessions and logical views are too high (50) and with a long user session it takes too much memory (up to 100m per user).
This default setting does not scale.

Here the default settings :

<context-param>
<param-name>com.sun.faces.numberOfViewsInSession</param-name>
<param-value>50</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.numberOfLogicalViews</param-name>
<param-value>50</param-value>
</context-param>

We should reduce this parameters to 5 or 1 if the back feature does not work in ajax.
