I think there was a post a few months ago that in recent AMD CPUs with up to date microcode, mitigations=off actually runs slower than leaving them on. This here seems to be the final nail in the coffin for turning them off, at least on AMD. In the very beginning we decided to turn them off on our fleet of Linux devices, but stopped after that post, even though we don't even run any AMD currently.

That is more a myth and makes no sense and is just the result of people benchmarking random nonsense. mitigations=off is 1-2% faster compiling open source software. On every not last gen silicon mitigations actually have a major impact on performance.
