  1. Rui, can you open a new Discussions thread at https://github.com/rui314/mold so we can transfer the whole conversation there? We could ask for advice from other project developers that have succeeded on their own journey.

  9. It's being discussed ( https://github.com/rui314/mold/issues/117 ) but haven't reached any conclusion. The problem is that the jobserver protocol assumes that one process is one job, and its model doesn't fit very well to programs such as…

  20. Osmos.io is built on Rust so that’s LLVM. No commercial vendor involved. There is Mold ( https://github.com/rui314/mold ) as an alternative but it doesn’t support MacOS yet and that’s a blocker for our team.

  22. https://github.com/rui314/mold would suggest otherwise. Massive speedups by multithreading the linker. I think traditional linkers just aren't highly optimised.
