The Principles of Java Application Performance Tuning

Not every application requires tuning. If an application performs as well as expected, you don't need to exert additional efforts to enhance its performance. However, it would be difficult to expect an application would reach its target performance as soon as it finishes debugging. This is when tuning is required. Regardless of the implementation language, tuning an application requires high expertise and concentration. Also, you may not use the same method for tuning a certain application to tune another application. This is because each application has its unique action and a different type of resource usage. For this reason, tuning an application requires more basic knowledge compared to the knowledge required to write an application. For example, you need knowledge on virtual machines, operating systems and computer architectures. When you focus on an application domain based on such knowledge, you can successfully tune an application.

Sometimes Java application tuning requires only changing JVM options, such as Garbage Collector, but sometimes it requires changing the application source code. Whichever method you choose, you need to monitor the process of executing the Java application first. For this reason, the issues this article will deal with are as follows:
