Adaptive Compressed Caching: Design and Implementation

In this paper, we reevaluate the use of adaptive compressed caching to improve system performance through the reduction of accesses to the backing stores. We propose a new adaptability policy that adjusts the compressed cache size on-the-fly, and evaluate a compressed caching system with this policy through an implementation in a widely used operating system, Linux. We also redesign compressed caching in order to provide performance improvements for all the tested workloads and we believe it addresses the problems faced in previous works and implementations. Among these fundamental modifications, our compressed cache is the first one to also compress file cache pages and to adaptively disable compression of clean pages when necessary. We tested a system with our adaptive compressed cache under many applications and benchmarks, each one with different memory pressures. The results showed perfor
