Have you enabled multiprocessing for several frames in the options? (so 
it renders several frames in parallel, as opposed to throwing all CPUs 
at one frame)

But anyway, I can only speculate: I am not sure if Aftereffects uses 
several threads per effect process. Otherwise, there might be 
dependencies within the processing graph that reduce performance (e.g. 
some effects must have finished rendering before it can process a new 
one). There might also be disk access that slows things down.
