Improve Cache Performance with high locality of reference

if users randomly and uniformly access data throughout the master data space a cache is useless, and in fact, it may actually degrade data access time. A cache is effective only if users maintain a high locality of references, that is, data references are spread over tiny areas of the data space, at least over a limited span of time.

L1 and L2 Cache

To be more specific, data to be cached must be at minimum as possible and to be accessed sequentially as much as possible. For example use a small array to store the checking conditions separately if only small portion of the conditions check will return true for next processing stage. If majority of the condition check will return true for next processing stage, the array should contain those extra data needed as well as condition variables.
