Plug POST performance

That’s effectively what we had in the second link in the top post:

Which we also had trouble getting good performance with. It was far below the ~300k we see with scala. Definitely better throughput with that code in your testing. How powerful a dev machine (I’m guessing just a laptop?).

I’m VERY interested in the fact you had sub-millisecond with Phoenix. One of the worst issues we saw in our testing was latency of over 9 seconds. The machine was 60% idle from a CPU perspective at the time and we were completely baffled by how that could happen.
