tl;dr:
numa memory policies

i don't really know much about numa
https://man7.org/linux/man-pages/man7/numa.7.html
it's not something i've ever had occasion to use. it seems sort of horrendously complicated? and more than a little bizarre. i mean, go read through these manpages...
probably not something i will ever bother to learn about or understand, since it seems like it might require specialized hardware to be worth a damn?

NUMA is not something you should waste time worrying about. If you don't know what it is, you don't need it.
I think the only usecase is massive servers with more than one CPU socket.
