Java EE 8 High Performance

By: Romain Manni-Bucau

Overview of this book

The ease with which we write applications has been increasing, but with this comes the need to address their performance. A balancing act between easily implementing complex applications and keeping their performance optimal is a present-day need. In this book, we explore how to achieve this crucial balance while developing and deploying applications with Java EE 8. The book starts by analyzing various Java EE specifications to identify those potentially affecting performance adversely. Then, we move on to monitoring techniques that enable us to identify performance bottlenecks and optimize performance metrics. Next, we look at techniques that help us achieve high performance: memory optimization, concurrency, multi-threading, scaling, and caching. We also look at fault tolerance solutions and the importance of logging. Lastly, you will learn to benchmark your application and also implement solutions for continuous performance evaluation. By the end of the book, you will have gained insights into various techniques and solutions that will help create high-performance applications in the Java EE 8 environment.

In this chapter, we looked at why logging is important to get a good and easy monitoring level. We also saw that a logging statement must be as minimally impactful on performance as possible so as not to defeat the optimization and coding you may have done elsewhere in your application.

This chapter gave you some common and simple patterns that can help you to rely, as much as possible, on the logging framework to make sure you maintain good performance.

Finally, we saw that several implementations may need to be configured in your applications, but that they will all share the same concepts, and that it is possible to rely on a single API, or even a single implementation from multiple APIs.

At this point of the book, you know what Java EE does and how to code and monitor an application. Now it is time to look at how you should approach a benchmark. This will be the topic...
