This topic describes the benefits of tuning for optimal performance, highlights the tunable parameters of the major WebSphere Application Server components, and provides insight about how these parameters affect performance.
Performance tuning can yield significant gains in performance even if an application is not optimized for performance. However, correcting shortcomings of an application typically results in larger performance gains than are possible with just altering tuning parameters. Many factors contribute to a high performing application.
The tuning guide focuses on server tuning. If you want to tune your applications, see the Performance: Resources for learning article for more information about application tuning.
Each WebSphere Application Server process has several parameters that influence application performance. You can use the WebSphere Application Server administrative console to configure and tune applications, Web containers, Enterprise JavaBeans (EJB) containers, application servers and nodes in the administrative domain.
Each parameter description: explains the parameter; provides reasons to adjust the parameter; discusses how to view or set the parameter; as well as indicates default and recommended values.
