glibc 2.37 contains a number of improvements to the memcmp routines for server-grade AArch64 implementations (in particular, graviton3). They should be backported to jammy and focal, as the LTS releases are by far the most used on servers.
[test case]
TODO
[Regression potential]
This could potentially impact performance on other, non-server-grade arm64 platforms such as RPi. We'll need to run tests against such machines to check impact.
