Memory Bandwidth

Metric Description

This metric represents a fraction of cycles during which an application could be stalled due to approaching bandwidth limits of the main memory (DRAM). This metric does not aggregate requests from other threads/cores/sockets (see Uncore counters for that). Consider improving data locality in NUMA multi-socket systems.
