It would be awesome to use mold to build.

What do you think about?

Ah, yes, I think that's a good idea. Not sure how easy it is to integrate in this musl setup and haven't played with it personally, so a PR for an initial setup of this would be helpful!

Would ideally want to test it a bit to ensure that a normal setup works / non-breaking (as they claim), and verify that it is faster to link in a simple webapp case, but if those two things are true, then it would make sense to use here as a default.

I think also starting with lld first will be good: https://nnethercote.github.io/perf-book/compile-times.html#linking.

If switching the base image to Fedora this is quite easily (along with mimalloc in a related issue) as all have packages available.

I haven't checked, but presumably modern ubuntu releases might package these too (which releases are packaged is hit/miss, Fedora's latest release surprisingly has an older package for protoc than Ubuntu Noble does).

That said Ubuntu as a base is a common choice used for images that build native deps like this image does in it's Dockerfile. If anyone is extending the image, that'd also be a breaking change 😓
