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.

Summary

In this chapter, we saw that a benchmark is something you need to prepare before ensuring you can benefit the most from the benchmark time, and that it requires some organization. We also saw that to be useful you need to extract, from the work done, the conclusions it implies. This is really a scientific procedure—but an easy one—and you need to respect it if you want to optimize your time.

The next and last chapter will go one step further and look at how to reduce the distance between the development and the benchmark to reach a continuous performance evaluation, making your benchmark no longer harmful, since everything is already prepared and under control.
