Optimisation happens in release builds. I assume when people talk about compilation speed they mean debug builds because those are the ones you have to wait for. For me the biggest hurdle to adopting Rust is that rust-analyser turns my laptop's fans up to 11. I don't know whose problem that is, but it doesn't happen with other languages, and my black box impression of rust's compilation infrastructure is that it's fucked up.
