Powerful processor is all about moving data in a short time possible: Big Data. It's not just about Java and .Net.<p>You could look at 3D XPoint and NVRam instead where data lives, those have cut down to 1 digit latency as claimed by Intel or Micron. Still Java 9 should be what you're looking at, lastly, Erlang for lowest latencies.<p>If Sun have produced proprietary microprocessor for Java it did before, it would have been a different world for us now as far as I heard it has the native performance. It's cost and time effective to buy newer hardware than improves coding to squeeze as much performance as possible.<p>In fact, general purpose processors we know is not efficient, it uses lot of watts when moving data within the microprocessors. I let the expertise do the talks.
