We propose a new cache management policy, namely, Adaptive Replacement Cache (ARC), that has several advantages. In response to evolving and changing access patterns, ARC dynamically, adaptively, and continually balances between the recency and frequency components in an online and selftuning fashion. The policy ARC uses a learning rule to...
