Why am I interested in Elixir?

For CPU intensive tasks, performance _is_ close to Ruby, while both Ruby and Elixir are far behind Go. Soft realtime doesn't mean fast, it just means good std deviation on response time and not a lot of missed deadlines. Fortunately as the article points out, there's always Rustler if you need to optimize while still keeping BEAM crash proof.

That being said, I agree that performance for certain IO intensive applications like web servers is very good, way better than Ruby. Subjectively Phoenix feels way, way faster than Rails in development and is much more performant in production.

Yeah, but how many companies do you know of that perform heavy computations in such large scale that their choice of programming language has a noticeable effect on the result?

I mean, it might matter for tech giants like Google, who need to squeeze every bit of processing power out of their CPUs. For almost everyone else, it will be a non-issue.

It's just that when you say "performance on par with Go", people might imagine you could write a 3D engine in Elixir, which obviously isn't the case.
