How has using Crystal been, anyone using it in production?

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.

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.

It's Ruby like syntax is awesome. It reads like psuedo code.

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.

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.

Roc?

They're unfortunately in the middle of a compiler rewrite from Rust to Zig right now though

Doesn't look like it fully supports the language or ecosystem, with partial support for 1.21 version.

I don't understand... Isn't that golang?

I think V might be what you’re looking for?
