JBoss AS 5 Performance Tuning

By: Francesco Marchioni, Jason Savod

Overview of this book

Today's organizations need to deliver faster services to a large set of people and businesses. In order to survive this challenge, enterprises need to optimize the performance of their application server along with its components and hardware. Writing faster applications is no longer just an option for your products; it's an imperative requirement, which you cannot ignore. JBoss AS 5 Performance Tuning will teach you how to deliver fast applications on the JBoss Application Server and Apache Tomcat, giving you a decisive competitive advantage over your competitors. You will learn how to optimize the hardware resources, meeting your application requirements with less expenditure.The performance of Java Enterprise applications is the sum of a set of components including the Java Virtual Machine configuration, the application server configuration (in our case, JBoss AS), the application code itself and ultimately the operating system. This book will show you how to apply the correct tuning methodology and use the tuning tools that will help you to monitor and address any performance issues. By looking more closely at the Java Virtual Machine, you will get a deeper understanding of what the available options are for your applications and how their performance will be affected. You will learn about thread pool tuning, EJB tuning, JMS tuning, Enterprise Java Beans, and the Java Messaging Service. The persistence layer and JBoss Clustering service each have a chapter dedicated to them as they are two of the most crucial elements to configure correctly in order to run a fast application. You will also learn how to tune your web server, enabling you to configure and develop web applications that get the most out of the embedded Tomcat web server.

Profiling your applications with Eclipse Test and Performance Tools Platform (TPTP) Project

In the first chapter, we have stated that the application code is responsible for about 75% of the performance of the application itself; that way we should consider adding a specific tool which is able to pinpoint hot points and bottlenecks in your code.

The choice of the tool for application profiling was not an easy one for me, mostly because there are actually many good products available in the market. One in particular, JProfiler (an evaluation version is available at:, has a very intuitive GUI that helps you find performance bottlenecks, pin down memory leaks, and resolve threading issues.

However, in the last few years a new open source profiler platform became popular across Eclipse developers: the Eclipse Test and Performance Tools Project. This project addresses the entire performance life cycle and can be considered the most valuable...
