In NUMA (non-uniform memory architecture) machines, memory requests missing LLC may be serviced either by local or remote DRAM. Memory requests to remote DRAM incur much greater latencies than those to local DRAM. It is recommended to keep as much frequently accessed data local as possible. This metric shows percent of remote accesses, the lower the better.

A significant amount of DRAM loads were serviced from remote DRAM. Wherever possible, try to consistently use data on the same core, or at least the same package, as it was allocated on.
