Answer 1

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

Answer 2

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.
