The performance of cache memory is frequently measured in terms of a quantity called Hit ratio.
Hit ratio = hit / (hit + miss) = no. of hits/total accesses
The performance of cache memory is often measured in terms of a quantity called "hit ratio" or "hit rate." The hit ratio represents the percentage of memory accesses that result in a cache hit, where the required data is found in the cache. The complement of the hit ratio, known as the "miss ratio" or "miss rate," represents the percentage of memory accesses that result in a cache miss, where the required data is not found in the cache and must be fetched from a slower main memory.
The hit ratio is an essential metric in evaluating the effectiveness of a cache system. A higher hit ratio indicates better cache performance, as a larger proportion of memory accesses are satisfied by the faster cache memory rather than having to fetch data from the slower main memory.
