The tuning items differ as per the type of application. The table below describes the tuning items for each component of the application.

Table 8‒1: Tuning items of an application consisting of Servlet and JSP (Web application)
Tuning Items	Available functionality	Reference
Optimizing the number of request-processing threads of the Web container	Control of the number of request-processing threads in the Web container	8.3.3
Optimizing the number of concurrent executions	Concurrently executed thread control in the Web application (each Web container, Web application, or URL group)	8.3.4
Optimizing the method for accessing the database	Connection pooling	8.5.1
Optimizing the method for accessing the database	Statement pooling	8.5.2
Setting the timeout	Setup of timeout in the Web front-end system	8.6.2
Setting the timeout	Setup of timeout of method execution of business application	8.6.7
Optimizing the operation of Web application	Separation of the deployment of static contents and Web application	8.7.1
Optimizing the operation of Web application	Caching static contents	8.7.2

Table 8‒2: Tuning items of application configured by Enterprise Bean
Tuning items	Available functionality	Reference
Optimizing the number of concurrent executions	Pooling of Stateless Session Bean instances	8.3.5
	Session control of Stateful Session Bean
	Pooling of Message-driven Bean instances
	Control the number of concurrent executions with CTM^# (when using CTM)	8.3.6
Optimizing the method of invoking Enterprise Bean	Use of local interface	8.4.1

#: Applicable only for the Stateless Session Bean.

The following table describes the tuning items of CTM operation that can be set up in systems that use CTM. You can use CTM when Stateless Session Beans configure an application.
