Abstract: At present, there are several tools designed for measuring the performance of Web server, such as TPC-W, SPECWeb99, WebStone, etc. These measurements are based on HTTP connections and reflect the performance at the Web server level. But until now, there is no idea of the performance of Web-based application system. It is obvious that there are many differences in performance between Web server and Web-based application system. People can't use the same methods to evaluate the performance of them. This paper analyzes the characteristic of Web-based application system, and gives two important concepts: user operation (UO) and user operation mix. On the basis of them, it primarily defines a set of terminology and performance metrics for Web-based application system, such as throughput, response time, degree of the complexity of user operations and concurrent user. All of them are defined at the application level. Furthermore, it describes the design of the performance evaluating system and proposes two measurement models: real workload measurement and simulated workload measurement. In simulated workload measurement it also explains some problems on the workload generation.
