Split locks are weird. It’s never been obvious to me why you’d want to do them unless you are on a small core count system. When split lock detection rolled out for linux, it massacred perf for some games (which were probably min-maxing single core perf and didn’t care about noisy neighbor effects).
Frankly, I’m surprised split lock detection is enabled anywhere outside of multi-tenant clouds.
