Can you translate the word "paused" into a wait event? What is the session waiting for? Did you look into V$SESSION_WAIT? Is there any difference in the execution plans? Just a word of advice, disabling the primary key is usually not a good idea, because it might help you with distinguishing one record from another. Without the primary key it's much harder to tell records apart.
