Mold 1.0: the first stable and production-ready release of the high-speed linker
FWIW, the author is also the original author of LLVM's "lld" linker, and has written multiple C compilers.That makes them the author of both of the two fastest linkers in existence, AFAIK. This person has a very impressive resume.https://github.com/rui314/mold/blob/main/docs/design.md  > "Concretely speaking, I want to use the linker to link a Chromium executable (~1.8 GiB in size) just in 1 second. LLVM's lld, the fastest open-source linker which I originally created a few years ago, takes about 12 seconds to link Chromium on my machine. So the goal is 12x performance bump over lld. Compared to GNU gold, it's more than 50x."

There is good discussion as well in this prior post, and Reddit thread with the author in it a while back:https://news.ycombinator.com/item?id=26233244https://www.reddit.com/r/cpp/comments/kxvw5c/mold_a_modern_l...
