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.

Welcome to scientific tuning

Today tuning has evolved to the rank of "science", first and foremost because it's supported by a vast collection of tools which can help you to systematically fix your performance issues.

So, before entering the tuning arena, we will install some nice software on your machine which will be used across the examples of this book. As we are embracing the open source philosophy, we have chosen to focus on high quality open source software, so your only investment will be the price paid for this book. You can still consider vendor alternatives, which often provide sales support and engineering staff trained to make the software have a less-daunting road to getting up and running.

In the first part of this chapter, we will learn about profiling the Java Virtual Machine (JVM), focusing on VisualVM, a powerful tool developed by Sun engineers.

In the next section of the chapter, we will learn about the Eclipse Test and Performance Tools Platform suite (Eclipse TPTP) which...
