What have you tried doing to measure this so far? – RedFilter Sep 20 '12 at 19:05

It's not recommended to use analyze to gather statistics (from 8i onward) because CBO(cost base optimizer) is build to recognize statistics that have been gathered using dbms_stats. So dbms_stats is a preferable way to gather statistics.
