Comparing Languages for Engineering Server Software: Erlang, Go, and Scala/Akka [pdf]

There were many languages that we would like to have considered. We do expect the performance of Elixir to be pretty similar to Erlang as it runs on the same VM (BEAM).

With regards the "alternatives considered", Section 2 outlines key characteristics of server languages, and Table 1 analyses a selection of languages against these characteristics.

We welcome others to report results for other languages using the benchmarks.

Hi Phil,

One thing you might find interesting - a small, crude experiment suggests that changing maxBlocking.erl to use process hibernation for those dormant processes could almost double the max number of processes Erlang can support.

I changed maxBlocking.erl's final few lines to read

    p() ->
        erlang:hibernate(?MODULE, q, []).
    q() ->
        receive
            "hello" ->
                io:format("Hello")
        end.

RabbitMQ uses hibernation in many places to reduce memory usage when many resources are being managed by the server.

Thanks for the info. We're not ninja developers in any of the languages.
