Abstract
One example method includes a cache eviction operation. Entries in a cache are maintained in an entry list that includes a recent list and a frequent list. When an eviction operation is initiated or triggered, timestamps of last access for the entries are adjusted by corresponding adjustment values. Candidates for eviction are identified based on the adjusted timestamps of last access. At least some of the candidates are evicted from the cache.
