摘　　要：网络应用的飞速发展使得网络服务器过载的情况变得日益突出，过载情况下服务器性能的测试对于服务器性能研究具有十分重要的意义，然而常用的测试方法却无法产生实验所需要的http流量。通过对http连接的建立过程和现有Web测试工具对过载情况下服务器能测试时所面临问题的分析，在sclient2的基础上经过改进和优化，实现了sclient_improve测试工具，采用非阻塞I／O的方式产生http请求、中央控制的分布式测试方法，符合真实网络环境的请求分布，实现了Web服务器在过载情况下性能的准确测试。With the rapid development of the application of network, the problem of web server overload becomes more and more urgent, so testing the performance of web server under overload have important meaning for web server research, however, common tools can not create enough http flux needed in test. Through the analyses of the process in building http connection and the difficulty in testing the performance of web server under overload, the sclients2 is optimized and a tool - - sclient_ improve is implemented, using non - block I./0 technology and distributed test method in central control. Sclient improve can simulate the request contribution of the real network environment and can accurately test the performance of web server under overload.
