基于LoadRunner的Web系统性能测试与优化

Performance Test and Optimization of Web System Based on LoadRunner

为了在软件产品发布之前确保软件质量,软件测试的重要性越来越受到人们重视。以专项能力管理系统为基础,阐述了软件测试的方法和过程以及测试脚本开发过程中事务和集合点的插入。按照统一标准测试Web对各种请求的响应时间,并结合LoadRunner性能测试工具对性能测试的两个重要指标,即响应时间和并发用户数进行研究,给出可靠的性能评价。使用LoadRunner进行测试分析可快速找到系统瓶颈,并通过结果分析采取相应的优化方案,在保证并发用户数不变的前提下再次进行测试。在虚拟用户数量相同的情况下,优化前比优化后的响应时间减少了10%,系统性能得以提升。

The importance of software testing has been paid more and more attention to in order to ensure the quality of the soft- ware products before the release of the software, to ensure that the software products meet the performance needs. On the basis of special ability management system, the method and process of software testing and the insertion of transaction and rendezvous during the development of test script are expounded. This paper tests the Web response time of various requests with the unified standard and combined with LoadRunner performance testing tool response time and the number of concurrent users of two im- portant indicators of performance test are studied. The performance evaluation is given reliable. By using the method of Load- Runner test and analysis, the system bottleneck can be found quickly, and the corresponding optimization scheme is adopted through the result analysis. On the premise that the number of users remains unchanged to test again. The response time after optimization is reduced by 10%, so the performance of the system is improved.
