Start components as needed Websphere Application Server ND 8.5.5

Select this property if you want the server components started as they are needed by an application that is running on this server.When this property is selected, server components are dynamically started as they are needed. When this property is not selected, all of the server components are started during the server startup process. Therefore, selecting this option can improve startup time, and reduce the memory footprint of the server, because fewer components are started during the startup process.Starting components as they are needed is most effective if all of the applications, that are deployed on the server, are of the same type. For example, using this option works better if all of your applications are Web applications that use servlets, and JavaServer Pages (JSP). This option works less effectively if your applications use servlets, JSPs and Enterprise JavaBeans (EJB).


You can improve system performance if you configure some of your application servers, such that each of their components are dynamically started as they are needed, instead of letting all of these components automatically start when the server starts. Selecting this option can improve server startup time, and reduce the memory footprint. Starting components as they are needed is most effective if all of the applications that are deployed on the application server are of the same type. For example, using this option works better if all of your applications are web applications that use servlets, and JavaServer Pages (JSP).
