I bet you'd see speedups if you rewrote in C++, too.

  Good point, but what is the comparative effort for both of those rewrites making similar performance improvements, and what skill level in the coder is needed to realize those similar improvements? E.g., will the C++ rewrite for X improvement take longer, or require a more highly skilled programmer, or would the Rust programmer require some high level of expertise to yield the results but a junior C++ guy/gal could knock it out quickly? Has anyone done real comparisons of this sort, such as taking software package X and assigning a performance rewrite to a junior Rust dev, a senor Rust dev, a junior C++ dev and a senior C++ dev, giving each a couple weeks then checking the yielded performance? Also, how does this interact on teams? It's been a long time since I've written any C++, and I've not tried Rust, but it seems some of the Rust safety features make it harder for devs to step on each other's toes.

  Not sure your point. Going from C++ to Rust, is what I meant.

    Parent may have meant that the second implementation might perform better, even if it’s in the same language, because you learn from the first implementation.

      Precisely. The old “build one to throw away”
