Abstract
Various embodiments for improving hash index key lookup caching performance in a computing environment are provided. In one embodiment, for a cached fingerprint map having a plurality of entries corresponding to a plurality of data fingerprints, reference count information is used to determine a length of time to retain the plurality of entries in cache. Those of the plurality of entries having a higher reference counts are retained longer than those having lower reference counts.
