Compile times generally take longer with Rust. It's a trade-off you're making when using anything rust related, but in exchange, you get some pretty sweet runtime perf. But with efficient caching of crates you can claw back a lot of time in CI.
doesnt that determine runtime performance for web apps, unless the browser is running rust natively or maybe wasm, I don’t see how javascript for example would be more performant just because I configured it in rust
