L2 Miss Count

Metric Description

The L2 is the last and longest-latency level in the memory hierarchy before the main memory (DRAM) or MCDRAM. Any memory requests missing here must be serviced by local or remote DRAM or MCDRAM, with significant latency. The L2 Miss Count metric shows the total number of demand loads that missed the L2. Misses due to the HW prefetcher are not included.
