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.

Scale Up – Threading and Implications

Scalability has always been a concern for Java and, thus, a thread-related API was introduced in Java version 1.0. The idea is to be able to benefit from the most modern hardware updates in order to parallelize the processing of applications.

Being able to handle multiple requests in parallel is crucial for a Java EE server to scale, but in our modern Java world, you also need to be able to control your own threads. Also, Java EE introduced the required API to do it in good conditions.

In this chapter, we will go through the following topics:

  • Java EE threading model
  • Data consistency across threads
  • Java EE hidden thread usages
  • How to integrate reactive programming with the Java EE programming model
