摘要： 分析现有在线事务处理(OLTP)类应用评测方法，提出一种基于Spirent的Web应用性能评测方法。采用平均事务响应时间、待测系统资源利用率和每秒事务数作为主要测试指标，将Web服务器和数据库服务器作为一个整体应用，综合评测OLTP类Web应用的软硬件性能，并快速定位Web应用系统的性能瓶颈。测试结果表明，该方法能将Web应用的系统性能提高40多倍，响应时间降低10多倍。

Abstract: This paper analyzes existing On Line Transaction Processing(OLTP) test methods, presents a Spirent-based Web application performance evaluation. Web server and database server as a whole and comprehensively evaluates the hardware and software performance of OLTP applications by testing Transaction Response Time(TRT), Resource Utilization(RU) of system and Transaction Per Second(TPS) of Web applications. This method can provide the guideline to chose and buy or design and deploy high performance computers. And it rapidly discovers the performance bottlenecks of a Web application, which can provide guidance for Web application optimization. Test results show the method improves the Web performance by more than 40 times, and reduces the response time by more than 10 times.
