Crystal performance is close to Go-lang. It's just very fast across the board.

Consequently, just like Go-lang, it beats Ruby by an order of magnitude on pretty much any benchmark.

Newcomers often assume Crystal must be sluggish like Ruby because "how could a language with such a convenient syntax be so fast", but it really is not.

I know Go is known for it concurrency, does Crystal come close to that aswell?

in fact Crystal concurrency is the same with Go, both using coroutine technique. though Go should be more performance because it is built for that feature.
