I didn't get why he doesn't see barely any improvement using mold, while mold's advertising/benchmarks show 1-2 magnitudes of improvements over gold, and still at least 50% vs llvm. Reading through mold's nice docs I could only explain that by him not utilizing multiple cores (molds actual strength besides other things), but seems pretty unlikely. Who can explain?

For the 17k SLOC project, link times were already under 100 milliseconds without mold. (EDIT: Actually linking took 129 milliseconds with GNU ld.) There are other, bigger bottlenecks to deal with.

As a project grows larger, link times become more noticeable, and mold starts to help.

Oh sorry you pointed that out below, thank you for doing again!

I actually pointed it out in the article when I compared GNU ld with Mold. =] And I was actually wrong in my comment; run_linker took 129 ms, not under 100 ms. https://quick-lint-js.com/blog/cpp-vs-rust-build-times/#opti...
