摘　　要：JavaEE Web应用系统的复杂性极容易导致性能问题,其中服务器端是性能问题产生的主要根源。针对服务器环节,基于"由外而内,由表及里,层层深入"的基本原则,提出一种系统化的性能诊断思路和流程,从用户视角、资源视角和组件视角逐层深入,分别从用户事务、系统资源、Web资源和页面组件4个层次阐述性能诊断的策略,为同类系统的性能诊断工作提供参考。The complexities of JavaEE Web application system easily lead to many performance problems which are mainly caused by servers.The systematic diagnosis process and solutions for servers are presented based on the basic principal described by＂From outside to inside,from surface to core,breakdown step by step＂.Three angles of view such as user experiences,resources and components are presented to drilldown the problems step by step.Then the strategies of performance diagnosis are discussed from four aspects including user transactions,system resources,Web resources and page components.Some good experiences are put forward for similar projects of performance diagnosis.
