A Home windows Server NUMA node optimizes how CPUs and reminiscence work together to enhance efficiency and enhance pace in multi-processor programs. It gives sooner entry to “native” reminiscence for particular processors, which might take longer when connecting to “distant” (farther away) reminiscence linked to different nodes.
