On NUMA systems allocated memory is striped across local and non-local =
banks in order to have consistent performance in case the task is =
rescheduled to a different CPU socket.
When a process is pinned to a single CPU socket with cpuset having the =
memory allocator prefer local banks would probably improve performance. =
Default system behavior would stay the same and the optimization would =
only be triggered on big multi socket systems when administrator used =
cpuset (command mostly used for performance optimization anyway).

Is this something currently implemented in FreeBSD? Is this even a good =
idea?=
