Multi Tier Web Application Performance Testing: A structured approach is critical to multi tier web application performance testing. Evaluating your software environment from the top down and using the scientific method of one change per experiment is the most efficient use of your efforts in java source code analysis.

This article is the second of two that present a systematic technique for optimizing Java code, specifically addressing a three-tier architecture that is extensible to any multi-tier environment. First read J2EE Environment Tuning, which describes how to performance tune a J2EE environment. Complete those steps before you attempt to optimize the application tier on its own.

This document is an intermediate discussion of performance tuning. It is intended for software developers who have a minimum of one year of Java development experience, familiarity with developing test workloads, and use of performance and monitoring tools.
