      Description

      ICEfaces execution can be divided into a number of high-level
      phases. By profiling test applications and comparing the results
      against stock JSF, the hotspots will be revealed, allowing us
      to concentrate our efforts on the code requiring performance
      optimizations. We must beware, however, as some of the hotspots
      will be inherent JSF CPU sinks, giving no opportunity for
      optimization.

      Poor synchronization may lead to poor performance, and ICEfaces
      definitely applies more synchronization than stock JSF. We
      should look at each usage of synchronization to see if it is
      necessary and ensure that it rarely spans user sessions.

      How much CPU time is spent in each of the following phases?

       Initialization
         - does init occur exactly as necessary; i.e. we should
           make sure we're not parsing the page on every request
         JSP parsing
         Facelets parsing
       Output
         lifecycle.execute()
         lifecycle.render()
           component tree traversal
           - hot spots within components
           DOM diff
           DOM serialization
         receive-updates
         JMS update propagation
       Input
         restore view
         decode
         events
