The compiler is fast in that is compiles code quickly, just as Go and the execution speed of produced programs are similar to Go (depending on what abstractions you use).

It seems there are a bunch of languages in the fast but not quite as fast as C/C++ category: Java, C#, Go, OCaml, SBCL (Lisp), Haskell

(not GP)

But yeah everything is fast at runtime as well when you coming from JS and python.
