fib VS stack

I've typically found rust to be about 100x faster than Python for the projects I've ported. This is consistent with https://github.com/drujensen/fib.

Here is a similar benchmark but includes compile times. https://github.com/drujensen/fib

How? Do you mean how do I know it's slow? Because it takes longer to run.

Write a typical computation such as Fibonacci in Java and Erlang/Elixir and compare. Fortunately someone has already done this.

Elixir is 3x slower than C and 2x slower than Java for this single thread example.

Apparently this upsets people for me to point this out. However, I did not say that Elixir was slow in general or a bad choice. It's an excellent choice for problems which suit parallelization or which require reliable, consistent performance.

Since the parent poster had commented that adding this multi-module dispatch would not be performant, I merely pointed out that the single thread peformance was already slow (as in, why worry too much about the performance cost of the multi dispatch suggestion).

Is there some advantage over repos that also show the results ?

I had most of these concerns when I was early learning the language. I found it annoying to have everything in modules. Now, however, I've come to appreciate the organization and structure that this forces upon the programmer.

It makes me structure my code and group related concerns at time of writing.

And with .exs files, you can have multiple modules in one file for quick scripting.[0]
