The Performance Tuning Process

The performance you get out of a messaging application depends on the interaction between the application and the Message Queue service. Hence, maximizing performance requires the combined efforts of both the application developer and the administrator.

The process of optimizing performance begins with application design and continues on through tuning the message service after the application has been deployed. The performance tuning process includes the following stages:

• Defining performance requirements for the application

• Designing the application taking into account factors that affect performance (especially tradeoffs between reliability and performance)

• Establishing baseline performance measures

• Tuning or reconfiguring the message service to optimize performance

The process outlined above is often iterative. During deployment of the application, a Message Queue administrator evaluates the suitability of the message service for the application’s general performance requirements. If the benchmark testing meets these requirements, the administrator can tune the system as described in this chapter. However, if benchmark testing does not meet performance requirements, a redesign of the application might be necessary or the deployment architecture might need to be modified.
