COMPARATIVE PERFORMANCE EVALUATION OF E-COMMERCE TECHNOLOGIES: A TPC-W-BASED BENCHMARKING TOOL

摘要

E-commerce systems are an important new application area in which maintaining good performance under scaling workloads is crucial to business success. The TPC-W benchmark is a benchmark designed to ex-ercise a web server and associated transaction processing system in representative e-commerce scenarios. Whilst the benchmark specifies the architecture of the system, and the form of the interactions between users, web server and underlying database, it does not stipulate the supporting technology used to communicate between the web server and the database. In this paper we describe a tool which has been developed to allow compara-tive benchmarking of different technologies with minimal re-implementation. The tool implements the TPC-W specification in a modular fashion which allows different application servers to be inserted and experimented upon. The use of the tool in the comparative benchmarking of Java Servlets and PHP is demonstrated.
