I used it in production for a client last yr and i compared that with a go implementation. The concurrency support of crystal on a 40 Core machine beast the socks off golang. Crystal both maxes out all the cores to a high degree, on file io and overall speed of execution. The time taken to do the same task Crystal; beats go by a significant margin while being so easy to write. And go is a easy language to write but Crystal is so much more easy to read because of Ruby syntax inheritance.
Can second about the concurrency syntax! Did a small comparison with Go a few years back [1].
I my tests I have got the feeling it is causing a lot less gotchas with blocking go-routines and such. Not sure why that is though.
Surprised to hear about the multi-core performance though! That is super interesting.

What is the reason of such advantage over Go? The latter is known to be geared towards concurrency, and also for having a very fast GC.
My guess is LLVM. Crystal Uses LLVM for code generation while Go has their own compiler backend.
Go can also compile to llvm https://github.com/goplus/llgo
Though I am not sure how fast it is.
Doesn't look like it fully supports the language or ecosystem, with partial support for 1.21 version.
It's Ruby like syntax is awesome. It reads like psuedo code.
man, I wish for something like crystal but with a little more golang like syntax.
I hate OOP though, I may be wrong but crystal afaik is OOP. I wish for a non OOP golang-esque crystal alternative.
> something like crystal but with a little more golang like syntax... I wish for a non OOP golang-esque crystal alternative.
I don't understand... Isn't that golang?
Roc?
They're unfortunately in the middle of a compiler rewrite from Rust to Zig right now though
I think V might be what you’re looking for?
