[erlang-questions] Why so slow kmeans implementation

[Andrea Peruffo]

This:
https://github.com/andreaferretti/kmeans
is a benchmark of different languages on a kmeans clustering algo.

I made an implementation of it but is terribly slow...

A question is about the data structure "dict" I used, is that the proper
use case or there is anything better?
I have checked with "ets" but looks even slower...

Is there anything wrong with the provided implementation?

Thanks in advance.
