Bill EastmanAbstract
Pete Anderson will present methodologies for improving systems-level QA and pre-deployment testing processes of Java/JEE applications. When conducting load and stress tests for complex multi-tier applications, it is challenging to understand overall performance behavior. Workload generation tools provide controlled experiments and measure user experience from an external client perspective. Testers/developers really need to look inside the application at all tiers to develop a holistic picture of how various components both inside and outside the JVM interact, identify system weaknesses, and identify those lower level components which should be considered for further analysis and optimization The presentation will include a demonstration that will use load test results from sample applications. Methodologies for establishing a performance baseline and creating load experiments that can be used for troubleshooting (as opposed to simply benchmarking) will be discussed. Techniques for discovering the following will also be covered: Application internals that behave badly "Hot spots" and system bottlenecks Subtle cause-and-effect behaviors Components that have the most impact on scalability Important workload characteristics Key measurements to monitor in production
