Performance Analysis of a Multithreaded Web Server on Multiprocessor

摘要

With the current explosive growth of the Web traffic, we have witnessed significant performance problems in Web servers. This stimulated several research efforts to develop high-performance Web servers based on the multithreading technique. The resulting software architectures of those Web servers are largely classified into three categories: RBW (Request-Based Web server), TBW (Task-Based Web server), and TPW (Thread Pool-based Web Server). In this paper we introduce the architecture of these three approaches and present their benchmarking results on a 4-processor PC server running Linux. Unlike previous research efforts that were only focused on the static data (e.g., text and image files) in a single CPU machine, we have benchmarked three different architectures in a multiprocessor machine by using both static and dynamic data (e.g., CGI (Common Gateway Interface)) and by varying the number of CPUs, data sizes, and amount of CGI request rates.
