Secondary Storage Management for Web Proxies
World-Wide Web proxies are being increasingly used to provide Internet access to users behind a firewall and to reduce wide-area network traffic. Recent results suggest that disk I/O is increasingly becoming the limiting factor for the performance of web proxies. In this paper we study the overheads associated with disk I/O for web proxies, and propose secondary storage management alternatives that improve performance. We use a combination of experimental evaluation and simulation based on traces from busy web proxies. We show that web proxies experience significant overheads due to disk I/O. We propose several file management methods that reduce the disk I/O overhead overhead by a factor of 25 overall, resulting in a single-disk service rate that exceeds 500 (URL-get) operations per second.
