Interesting, thanks for sharing. In my case, which is mostly about lists crunching, Elixir is many tens of times faster than Python. With some optimizations the advantage becomes many hundreds of times faster even with 5 times larger amounts of data. For example, an imperative algorithm on a list of ~130k dicts in Python would take me about 20 minutes. Trying to rewrite it functionally and seeing the function just get stuck and never return is what made me switch to Elixir 
. In Elixir, with an imperative algorithm, I’ve been able to get done with a list of ~500k structs in ~200ms.
Your .exs script is ~1000ms for me, while .py one is ~500ms. Elixir 14.3/OTP 25, Python 3.10.7.
