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 is defined by the ratio of remote DRAM loads to local
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.
