Hello Shashi, A couple more recommendations:
* Follow Dan Allen's suggestions in these articles: http://www.jsfcentral.com/articles/speed_up_your_jsf_app_1.html and http://www.jsfcentral.com/articles/speed_up_your_jsf_app_2.html. Often, as someone else suggested, the problem is placing time-consuming code inside of getter methods that are referenced via the EL. * Time different parts of the life cycle -- this will verify whether or not the problem is really in the Restore View phase. You can do this by writing a simple PhaseListener or using something like PrimeFaces' FacesTrace ( http://primefaces.prime.com.tr/en/). Which application server and OS are you using? --- Kito D.
