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.

Chapter 6. Tuning the Persistence Layer

5th Circle of Hell: Wrath and Sullenness: Here lay unfortunate developers blaming the application server for poor performance while neglecting to use a Connection Pool.

Data persistence is a key ingredient of any enterprise application and it has been a part of the JDK API since its very first release. Most readers certainly agree that data persistence is the most common cause of bottleneck in your applications. Unfortunately, isolating the root of the problem is not a straightforward affair and requires investigating in many areas: from the SQL code, to the interfaces used to issue SQL statements. Other potential areas that might affect your data persistence are the database configuration and finally, the underlying network and database hardware.

For this reason, we have divided this chapter into three main sections in order to cover all factors which can drag the performance of your data persistence:

  • The first section introduces some principles of good...
