Not sure how relevant that this is to mainframe programming, but years ago when
I designed and executed
with a team of nine a data-heavy server in Unix optimized for multiple cores,
what we found was that
reroutable queuing of data from one simplistic processing engine to the next
(with reservoirs for data accumulation)
got the most performance. It was a much more productive approach in light of
memory, bus and i/o considerations than
executing an arbitrary design and trying to speed it up on the processor cores
themselves.
That architecture is more or less how OS/400 worked on its best days, btw.
