I am message passing thousands of financial ticks per second to hundreds of terminal-user consumers, each of which may wish to preselect filters that they wish applied to each series, or combinations of series. This is trivially easy to organize in Erlang&#x2F;OTP, it is trivially easy to scale, and I have no clue how I would organize it in Ocaml without going to message passing first principles, and in which case I would have to build the entire load balancing, PID and security infrastructure from scratch. Moreover I do not see how you do not see that multicore and multi-node are related. On Erlang, having two 8-core boxes is almost the same as having one 16-core box. Again, if there is something I am missing about the Ocaml environment I would be happy to know about it.
