Wild is a decent bit faster than mold at this point:
https://github.com/wild-linker/wild
(Benchmarks in the README.)
Rui mentioned today that he managed to speed up mold "about 1.5 times" while writing this paper https://x.com/rui314/status/2092486965186969699?s=20
Seems that some optimizations went to mold 2.42 and others are not yet released. Wild benchmarked mold 2.40 or 2.41
Excellent (pardon the pun!) link! :-)
I'm keen to follow along with Wild as their intent is to be incremental, and Zig recently announced incremental linking support. I'm also a fan as its cool to seen an Australian working full time on open source (I'm also Australian)
Edit to add: I think David's talk on Wild [0] is an interesting summary of what a linker is and why its hard to make incremental
