I haven’t tried debugging with lldb in some time so I don’t know whether it has improved significantly, but couldn’t the 9% also include that?

It could be the case. There are multiple separate efforts to improve the debugging experience in production (improving monitoring, cheap profiling, improving logging, encoding more info in the DWARF output), but all of those will take some time to reach the same level of quality that, for example, Java has today.

I am somewhat pessimistic because LLVM is significantly behind GCC in debug information quality (for example, see https://robert.ocallahan.org/2018/11/comparing-quality-of-de...) and there is limit to what Rust can do about it short of fixing LLVM.
