I've build-tested on all architectures in this PPA: https://launchpad.net/~dannf/+archive/ubuntu/mthp/+packages
I manually tested on a few systems, timing a full kernel build w/ the Ubuntu config in a tmpfs (both to stress the system, and look for performance differences).
- ppc64el / Power9 - no performance difference - x86 - AMD EPYC/Naples - 11% improvement - Ampere AltraMax (-generic) - 19% improvement
