Worth pointing out that there's no dynamic allocation or dispatch in any of the examples (afaict), so all languages that use a GC get around having to do any reference tracking or collection. Which explains how Go/Java/C++ can track C performance so closely. I wouldn't be surprised if they'd all run almost the same machine code in the end.
