针对当前Web通用服务器性能评测工具并不能满足Web集群系统性能评测的需要,该文的研发重点在于构造一个高性能的支持QoS的Web集群服务器评测工具WC-Stress(WebClusterStress)。它的特点包括:可组装的组件结构;支持Web集群的评测需要:如区分服务;支持细粒度的QoS性能评测:如资源优化调度算法的支持;支持新的Web访问特征:如自相似请求的产生。最后给出了此评测工具对笔者设计的一种新型Web集群服务器的测试结果。
According to the current Web universal server performance evaluation tools can not meet the needs of Web cluster system performance evaluation, the article focuses on the construction of a high-performance QoS Web server cluster evaluation tool WC-Stress (WebClusterStress). Its features include: assembly of components can be assembled; support Web cluster evaluation needs: such as differentiated services; support for fine-grained QoS performance evaluation: such as resource optimization scheduling algorithm support; support for new Web access features: such as self-similar request produce. Finally, this evaluation tool gives the author a new type of Web cluster server test results.
