Ok .. I'm not trying to rush you .. With that said, the increased number
of threads seems like a natural direction to take.. I would assume the
returns would diminish depending on the number of threads per the
hardware.. For instance , your addition of one thread might even harm
the boot time on some single core embedded systems ..
