WebMark:一个Web服务器性能测试工具

Web及其应用程序的普及使得Web服务器的性能测试变得越来越重要,而现有的测试工具都具有一定的适应性限制.总结了Web服务器性能测试的指标和原则,提出了一个更加合理的测试指标--加权响应时间.介绍了一个Web服务器性能测试工具WebMark.它用事件驱动的方式管理异步I/O,通过修改Client的TCP/IP协议栈来模拟Internet环境.使用它对Apache进行了全面测试,证明了研制WebMark这样一个功能强大的测试工具是十分必要的.

WebMark: A Tool for Testing Web Server Performance

In this paper, the metrics and principles of testing Web server performance are summarized, and a more rational metric, weighted response time, is proposed. A tool called WebMark is presented for testing Web server performance, which manages asynchronous I/O by event-driving mode and emulates Internet environment by modifying the TCP/IP stack of clients. The testing of the overall performance of Apache proves that developing such a powerful testing tool as WebMark is of great necessity.
