System and method for determining relative cache performance in a computer system

摘要

A system, method and computer program product which determines the relative performance of a local cache and renders the resultant performance increase (or in certain circumstances, the decrease) in cache performance of a stand-alone computer or networked "client" perceptible to the user in an especially intuitive manner. By accurately tracking and factoring in the times and amounts of data read from one or more source locations and the cache, the amount of time required to execute "read" operations without the cache can be determined. By dividing this time period by the actual time to execute the "read", the true relative performance of the cache may be determined.
