> ease/speed of prototyping, pure performance, a good concurrency model out of curiosity, which language + library/framework pairs do you think is a better tool than javascript + nodejs when evaluated along each of your 3 metrics? I moved from python + flask to nodejs a while ago, I still thing nodejs is better than python + flask, but I'm trying to move away from javascript on the backend.

I choose Rails for fast prototyping, recently Go if I want pure performance that I can't get from caching, and Elixir + Phoenix if I need a good concurrency model and/or high throughput, but don't necessarily care about the microseconds that can be shaved off with Go.

  That's interesting. I should do some real world benchmarks on Elixir vs Go for my own purposes. But I'd imagine if you really care about microseconds, you should use a language without GC. Rust would seem a good choice.

  I think the issue there for most is that you mentioned three different programming languages.

Clojure - if you're looking for a dynamically typed language with REPL driven development process - it can leverage the huge JVM ecosystem and the concurrency tools are best in class compared to mainstream languages. Performance often comes down to idiomatic vs optimized - but you can optimize stuff and there's always "drop to Java transparently" card if you hit a wall in some area.
