L3 Latency

Metric Description

This metric shows a fraction of cycles with demand load accesses that hit the L3 cache under unloaded scenarios (possibly L3 latency limited). Avoiding private cache misses (i.e. L2 misses/L3 hits) will improve the latency, reduce contention with sibling physical cores and increase performance. Note the value of this node may overlap with its siblings.
