WebFeb 19, 2013 · 6. This is a simplification, but, one of the primary reasons the cache increases 'speed' is that it provides a fast memory very close to the processor - this is much faster to access than main memory. So, in theory, increasing the size of the cache should allow more information to be stored in this 'fast' memory, and thereby improve … WebThe hit rate is defined as the number of cache hits divided by the number of memory requests made to the cache during a specified time, normally calculated as a percentage. Similarly, the miss rate is the number of total cache misses divided by the total number of memory requests made to the cache. One might also calculate the number of hits or …
