This is going to depend of your server, if it's using a multicore cpu that support Numa affinity. Type numactl --hardware and you'll check how it's the current configuration, for example:

available: 2 nodes (0-1) node 0 cpus: 0 1 2 3 4 5 6 7 node 0 size: 32733 MB node 0 free: 4027 MB node 1 cpus: 8 9 10 11 12 13 14 15 node 1 size: 32767 MB node 1 free: 20898 MB node distances: node 0 1 0: 10 21 1: 21 10

If you want to check performance with your application, just make sure that it's using the CPUs from the same numa node. You can check this using ps -aux ortop commands.
