    Abstract: The present invention relates generally to a method and system for efficiently identifying a cache entry for cast out in relation to scanning a predetermined sampling subset of pseudo-randomly sampled cached entries and determining a least recently used (LRU) entry from the scanned cached entries subset, thereby avoiding a comprehensive review of all of or groups of the cached entries in the cache at any instant. In one or more implementations, a subset of the data entries in a cache are randomly sampled, assessed by timestamp in a doubly-linked listing and a least recently used data entry to cast out is identified.
