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.

Preparing your benchmark

Preparing a benchmark is probably the most important task you will have to do. In fact, if you miss it, it is guaranteed the benchmark will be a failure and useless. Even if tasks are not very complicated in general, they will not be done by themselves. So take your time to ensure they are done before the benchmark starts.

Defining the benchmark criteria

A benchmark is always done to make sure we encounter a metric. Therefore, the first step of benchmark preparation is to clearly define this metric.

Defining a metric means clearly defining what is measured and how to measure it.
