They're sorted by highest delta, which makes it look so significant in the first moment.

Also, though one of golangs target was to get close to c-like performance, they never intended to be the "performance-killer" since the focus is also strong simplicity and productiveness.

Another angle where Rust is doing well is in peak RAM usage. Its memory usage is generally (although certainly not universally!) much lower in these examples.

Yeah, no doubt! As already written somewhere above, the GC is not cheap.
