Performance and Scalability Bottlenecks in J2EE Applications

Key Points

Presentation Abstract

The J2EE platform is quickly emerging as a standard for building enterprise applications. Although the platform has been designed to support high-performance applications, many organizations are discovering that their applications are failing to meet agreed upon performance criteria.

This talk addresses the common causes of performance problems in J2EE applications. Beginning with a discussion of the differences between performance and scalability, this presentation separately discusses both types of problems in J2EE applications, illustrated with some common real-world scenarios. We will also show how these types of problems can be detected and diagnosed in both a load-testing and production environment.
