The article is fine and has a lot of good points, but tries to avoid the main issue like a plague. So I will speak it here:
The slowness comes mainly from LLVM.

For many use-cases yes, but there are crates bottlenecked on different things than the codegen backend.
But I don't think that's the point. We could get rid of LLVM and use other backends, same as we could do other improvements. The point is that there are also other priorities and we don't have enough manpower to make progress faster.
Fair reply, thank you.
This is somewhat true but also a bit misleading. Lot of the problems comes from how rust interacts with it, and how are rust projects structured. This ultimately shows up as time in LLVM, but LLVM is not entirely responsible for it.
