15.1 Performance Planning

Section 13.7 is particularly relevant for J2EE projects. Continual load testing, valid test data, appropriate testing environments, good monitoring tools, and well-specified performance targets are all crucial to achieving a high-performing J2EE deployment. In addition, monitoring after deployment is strongly recommended to maintain good performance. Don't let the brevity of this section mislead youmaking a performance plan, emphasizing the aspects I've just listed, is the single most important indicator of success for a J2EE project's performance.
