On NUMA systems allocated memory is striped across local and non-local banks in

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?
Do you mean linux like numactl ? AFAIK, there is no such feature in the
FreeBSD.
