RustPython didn't adapt the optimization designs yet. One of the current major goal is this optimization: https://github.com/RustPython/RustPython/issues/3244

RustPython even cannot run `1+1` without calling `int.__add__` yet. And it is working on https://github.com/RustPython/RustPython/pull/4615

So it still has long way to go not C vs Rust but from the design level.
