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.
