Considering that it’s state of the art, you must have been doing it terribly wrong.

That confirms it.

That's just not true. Before you would run into all kinds of bottlenecks after 2-4 cores. I believe it was addressed in R13A[1].

Not after 2-4 cores. And R13A is 2009, that was 10 years ago. (Java 8 is 2014.)

Today’s Erlang (R22) MP support is practically the best, bar none.
