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 concept of microbenchmarking

The Java community has always adopted the creation of predictable and transparent program build practices. This is done to reduce the risk when developing software. Continuous delivery of strong code is only possible using the feedback obtained during the programming procedure. The first-to-know approach allows a programmer to understand the problems and then implement the solutions before the program is out for general testing.

All developers will need standardized tools and practices to get the necessary feedback to deliver strong code. There are already external tools that can be used to checkout the finalized code. What programmers need is the comparison of their techniques in real time, during the programming procedure. This is where the use of microbenchmarks has its importance.

However, microbenchmark techniques are not commonly used in...
