Robert I think you are onto something there, I did some cleaning up last 
night and it's rendering faster.

On another note,  AE actually rendered faster with Hyperthreading turned 
off (no multiprocessing).  The project I was rendering was a good blend 
of using still, video and Element 3D elements, the total time savings 
amounted to about 5%. I thought AE was past that turning hyperthreading 
off phase.
