(You may want to test ultrafast.)

(Complete, uncut console output missing.)

Sorry if I miss something but don't you agree that using 
two ffmpeg instances must produce an overhead?
I didn't test but I would expect that using only one 
instance saves a few cycles (which may or may not be 
enough to fix your problem).
