Java 9 High Performance

By: Mayur Ramgir, Nick Samoylov

Overview of this book

Finally, a book that focuses on the practicalities rather than theory of Java application performance tuning. This book will be your one-stop guide to optimize the performance of your Java applications. We will begin by understanding the new features and APIs of Java 9. You will then be taught the practicalities of Java application performance tuning, how to make the best use of garbage collector, and find out how to optimize code with microbenchmarking. Moving ahead, you will be introduced to multithreading and learning about concurrent programming with Java 9 to build highly concurrent and efficient applications. You will learn how to fine tune your Java code for best results. You will discover techniques on how to benchmark performance and reduce various bottlenecks in your applications. We'll also cover best practices of Java programming that will help you improve the quality of your codebase. By the end of the book, you will be armed with the knowledge to build and deploy efficient, scalable, and concurrent applications in Java.

Summary

Java 9 is a great update and contains excellent opportunities for Java community members who are looking to create even larger programs and applications. Its garbage collection methods are geared towards providing consistent pause times, even at the expense of requiring more computational power. G1GC becomes the default garbage collection method and allows the full use of the capacity of the 64-bit JVMs to use large heap regions.

In the next chapter, you will learn about microbenchmarking and understand how to optimize the code with it. You will also learn about Java Microbenchmark Harness (JMH) and understand how to set up JMH. We will see some practical examples of using JMH in a real project.
