>"It’s awesome that the images are pretty small, but a wide variety of software has been shown to run noticeably slower on Alpine compared to other distributions, in part due to its usage of musl instead of glibc"

Might you have any citation(s) for this? I have not heard this before. Could you elaborate on what some the "wide variety of software" is? Thanks.

I've heard that having shared libraries like glibc allows for commonly shared hotpaths to remain in the CPU cache, making it faster. Whereas in musl, since the binaries all have their own copies of procedures, they are more often kicked out of cache. I don't imagine it has a big impact on a container where you are only running one or two binaries. Perhaps in a desktop environment with hundreds or thousands of different programs running, it might make a difference.
