Abstract
Cache utility curves are determined for different software entities depending on how frequently their storage access requests lead to cache hits or cache misses. Although possible, not all access requests need be tested, but rather only a sampled subset, determined by whether a hash value of each current storage location identifier (such as an address or block number) meets one or more sampling criteria. The sampling rate is adaptively changed so as to hold the number of location identifiers needed to be stored to compute the cache utility curves to within a set maximum limit.
