JSF slowness after implementing Phaselistener

Question

I’m implementing the Phaselistener interface and now the system has slowed down. I was doing an analysis and saw that JSF is making repeated calls to a page that has only one panel with information coming from the database. Does anyone know what might be going on or have experienced this problem before? Is it possible to decrease the number of calls? Any tips?

Note: In the implementation of the Phaselistener methods I only put one System.out.println("") so the slowness is not caused by any code implemented in them.

I have already gone through exactly this problem. This is caused by setting up your file web.xml, where you should delete the following lines:

  <listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
  </listener>
