I think that’s primarily a Rust issue, not an LLVM issue. LLVM is at least competitive performance-wise in every case I’ve used it, and is usually the fastest option (given a specific linker behavior) outright. That’s especially true on larger code bases (e.g. chromium, or ZFS).

Rust is also substantially faster to compile than it was a few years ago, so I have some hope for improvements in that area as well.
