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.

The different types of Java profiling tool

If a program is plagued with slow service, the system unexpectedly crashes and is prone to hanging and pausing on its own, or takes up excessive CPU power and memory; the odds are that there are certain bugs in it that need to be removed as soon as possible. However, for debugging, it is necessary that you have the requisite data before you commence any rectification procedures.

Fortunately, there exists a vast number of tools that may potentially help provide all the necessary information that you need to be able to fix the program. Some of these tools may be part of the JVM itself, while some tools have been developed by third-party specialists.

We will look at some of the most simple ones that may prove to be helpful once the program or application (as the case may be) starts performing unexpectedly.
