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.

Monitor Your Application

When it comes to an application's performance, you will quickly need to know what your application does and get the metrics of performance. In this chapter, we will identify a few ways to get insights on applications.

Thus, in this chapter, we will learn how to monitor our application's behavior in order to be able to compare it with the response times and execution times we observe. This will therefore show you the following:

  • How to add monitoring or profiling to an existing application
  • How to read important figures corresponding to the monitoring of an application
  • How to ensure that the application performance is monitored and that any unexpected changes are visible
