NUMA Linux systems benefit from adding the memory affinity +maffinity option and this won't affect non-NUMA performance. On large multi-CPU systems adding +CmiSleepOnIdle reduces the threaded spinlock impact across shared memory and reduces the jitter of the metrics and also helps NUMA systems too.
