Abstract

In this paper we propose new caching and test their performance. We use Memcached platform to test the caching algorithm performance. Memcached is an extremely popular open-source, distributed key-value store system that powers several of the Internet's busiest websites such as LiveJournal, Wikipedia, Facebook and others. Currently, Memcached uses a trivial Least Recently Used algorithm for cache eviction decision-making. We describe modifications to the Memcached caching system and the introduction of alternate caching policies and benchmark them as well. 3 new caching algorithms are introduced and 2 new implementations of well-known algorithms are benchmarked as well. We discuss the caching algorithm and the simulation methods used in this paper. By introducing superior caching algorithms, we demonstrate a 10-20% improvement of hit rates. This feature has been sent to Memcached upstream and was met with positive feedback.
