摘　　要：分析了数据库的连接、构件或中间件的加载与卸载次数和线程的重复使用等影响分布式Web系统性能的主要因素,运用"池化资源"技术解决了这一问题。论述了"池化资源"技术及其对提高分布式Web系统执行效率所起的作用,探讨了CGI,Web API,ASP和MTS等常用中间件对"池化资源"技术的支持,分析了不同中间件技术对Web系统执行效率的影响。应用实例表明,在Win2000平台上结合MTS中间件开发的分布式Web系统,对"池化资源"技术有很好的支持,可使系统的执行效率达到最高。Three major factors that have obviously influences on the efficiency of the distributed Web system are analysed. The pooling technology is used to solve the above problems. The pooling technology and its influence on the efficiency of the distributed Web system is discussed. Then CGI, Web API, ASP, MTS mid-ware technologies are studied. It is summarized that different mid-wares have different supports to the pooling technology and have different influences on the efficiency of the distributed Web system. The application instance proves that the distributed Web system with MTS mid-ware in Windows 2000 supports the pooling technology well. The efficiency of the distributed Web system with pooling technology is the highest.
