ESP: An Efficient Storage Management Policy for Proxies

Abstract

With the enormous growth of the WWW, the Internet has seen a large volume of traffic, which introduces severe congestion and worsens our surfing experience. Proxy cache is a common solution to this problem. It reduces the traffic on the Internet and the response time for Web accessing. However with the potential growth of the WWW, the proxy is overburdened and that in turn increases the response time even more. In this paper we propose an efficient mechanism, ESP (Efficient Storage management policy for Proxies), to reduce the file operation and disk seek time in order to improve the performance of proxies. We implement ESP by modifying the source code of Squid. Squid with ESP shows a 100% performance improvement to the original Squid design.
