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.

After your benchmark

Once you have done your benchmark, you should have a database of your runs (the folder we talked about earlier with the reports, configuration, and so on). Now, to ensure you did the benchmark for a reason, there are few actions you should take.

In this section, we assume that you will do these steps after the benchmark, but you can do them during the benchmark itself. It is presented this way because it is something you can do offline, and if you have some costs associated with the benchmark, these are tasks you can postpone easily.

Writing a report

Normally, at this point, you have collected all the data corresponding to the hard work you did during the benchmark. It is quite important to aggregate this...
