A system, computer program product and method for reconfiguring a cache. A cache array may be created with one or more stacks of cache entries based on a workload. The one or more stacks may be ordered from most frequently used to least frequently used. The cache entries in each particular stack may be ordered from most recently used to least recently used. When a cache hit occurs, the cache entry requested may be stored in the next higher level stack if the updated frequency count is associated with the next higher level stack. When a cache miss occurs, the cache entry in a least recently used stack position in the stack with the lowest number of cache hits in the one or more stack positions tracked during a particular period of time may be evicted thereby allowing the requested information to be stored in the lowest level stack.
