I don't literally see my deps compile. It's just that compile time gets slower. (I wonder if it's related to the linker?) Is that still a bug? Would be happy to report it if so.

Ahh. I am less sure, but I would think that's expected, given that it has to link everything together into the final binary. You're gonna end up giving the linker more work to do, as you suspected.

If the slowless you're seeing is caused by the linker, which can very well be the case, consider using LLD as you can see significant speed improvements to the linking step. https://github.com/rust-lang/rust/issues/39915#issuecomment-618726211 https://github.com/rust-lang/rust/issues/39915#issuecomment-... https://doc.rust-lang.org/1.22.0/unstable-book/compiler-flags/linker-flavor.html https://doc.rust-lang.org/1.22.0/unstable-book/compiler-flag... If installed, you can run RUSTFLAGS="-Clink-arg=-fuse-ld=lld" cargo build --release

  Looked into this :) unfortunately I run Mac so there's nothing I can do here. Tempted to dual boot Ubuntu, though.

    It's a shame. I'm on the same boat and not being able to use lld adds a literal minute to my builds :-/
