Definition: A high L2 cache miss rate indicates that the running workload has a data set larger than the L2 cache. Some of the data might be evicted without being used. Unless all the required data is brought ahead of time by the hardware prefetcher or software prefetching instructions, bringing data from memory has a significant impact on the performance.
