Old tweet from Rui, but I saw it in a recent zig video and really liked the sentiment:

> my strategy is to increase the value of commons by, say, 100 and get 1 as a return, so bear with me. If you want to use mold for free, you can just do that. This is my open-source business strategy.

Wishing the best for Mold and Rui

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

(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.

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

We use mold as the default linker in the Stagex linux distribution. It shaved hours off our full tree build time.

Would use this at a fairly large company if we had windows and Mac support, probably could get budget to pay for the features it’s missing.
