It's well known Erlang is not suited for data science and number crunching. I'm curious why you even bothered, near every introductory guide I've read makes this clear.

So that's not a good example of Erlang/Elixirs performance which is hardly known to be 'slow'. The language and process/actor model is far faster than many other languages particularly in the web space.

The author's also mentioned heavy dependency on the actor model as a performance optimizing strategy and optimal code structure which is why it likely is worth fully exploring for the OPs problem.
