Adaptive Replacement Cache is an enhancement over the standard LRU cache in that tracks both frequency and recency of use. This avoids a burst in access to new entries from evicting the frequently used older entries. It adds some additional tracking overhead to a standard LRU cache, computationally it is roughly 2x the cost, and the extra memory overhead is linear with the size of the cache.
