It could, if it stopped doing a lot of things it does which the Go compiler doesn’t. Or of course if the Go compiler started doing them so it became a lot slower. One example is “full”monomorphization of generics. But there are lots of such examples. Usually though I find the Rust compilation speed a non issue, so long as “cargo check” and the IDE analysis is great, I just rarely compile to begin with.
