NUMA can be such a pain, especially because it's really difficult to account for in code, and all sorts of stuff you'd never think of can end up impacting your performance too, that usually you'd never even think of, e.g. the linux page cache.
With the way that processors are going, with this focus on increased core counts etc, NUMA is increasingly being important to understand and account for, as processors are getting more "NUMA-ish" (to borrow a co-workers apt description). Especially Neoverse/Arm CPUs, etc.
