For docker images, cgr.dev/chainguard/wolfi-base (https://images.chainguard.dev/directory/image/wolfi-base/ver...) is a great replacement for Alpine. Wolfi is glibc based. It's easy to switch from Alpine since Wolfi uses apk for package management with similar package names and also contains busybox like Alpine.

I’d much rather go with distroless, if its a choice.

But I think you can tweak musl to perform well, and musl is closer to the spec than glibc so I would rather use it; even if its slower in the default case for multithreaded programmes.

You can not, its allocator does thread safety via a big lock and that’s that.

Is it?

That’s far from the only situation where it’s slower though.
