As I said, the one example I have is a very popular TUI library and it's a lot less efficient than the popular alternative in at least 2 other memory-safe languages I tried.

that's why I wrote on avg

Well you threw as a belief that because Rust is advertised as fast, people implementing Rust libraries probably care about speed on average.

I don't see why they would care more, and in my experience they don't, on average.

No, I didn't throw that, though now that you say that, I certainly believe people using Rust care on avg more about speed.

Your experience is a singular event not representing the average.

My original opinion was that people should use more Rust to write more efficient software, because it's beneficial to humanity.
