any help will be appreciated...

Do you have any logic in your getters? As these will be called multiple times move all logic into methods that are called once.

Put in a Phase Listener like this one from Andy Gibson

Notice, that by default richfaces components use client side paging based on JavaScript, so when you load a page all data are read. Maybe initially your page shows lot of data (table, combos, tabs)?

Try to improve performace by creating server side paging.
