Cpanel one user slow , the other fast

http://serverfault.com – I have a blog service provider . On WHM we have two users , one of them is the main site with about 600 parked domains and lots of virtual subdomains with about 400,000 daily php hits + thousands of static file requests . The other account gets almost no visit compared to the big one ! Well everything was ok until 3 weeks ago , from that time one day the server is responsing extremly fast , the other day it takes seconds to load a single page that even does not use mysql . While sql queries seem very fast (in phpmyadmin) php is slow (or maybe litespeed) . ++++ my server load varies between 3 t (HowTos)
