Cooperative Caching Middleware

Cooperative caching can be used to co-manage cluster’s memory by using software communication to allow nodes to access each others memory. We have reexamined the question of whether a server built on top of a generic block-based cooperative caching algorithm can perform competitively with locality-conscious servers. Specifically, we have compared the performance of a cooperative caching-based web server against L2S, a highly optimized locality-conscious server. Our results show that by modifying the replacement algorithm of traditional cooperative caching algorithms, we can achieve much of the performance provided by locality-conscious servers.
