Wild is a decent bit faster than mold at this point:

https://github.com/wild-linker/wild

(Benchmarks in the README.)

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

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

I guess this sentence from the Wild readme is also relevant:

  Mold is already very fast, however it doesn't do incremental linking and the author has stated that they don't intend to.

To be clear, Wild also doesn't do incremental linking yet but plans to in the future

Excellent (pardon the pun!) link! :-)
