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.

Thread synchronization

We have collected enough people and resources such as food, water, and tools for the pyramid building. We have divided people into teams and assigned each team a task. A number (a pool) of people are living in the nearby village on a standby mode, ready to replace the ones that got sick or injured on their assignment. We adjusted the workforce count so that there are only a few people who will remain idle in the village. We rotate the teams through the work-rest cycle to keep the project going at maximum speed. We monitored the process and have adjusted the number of teams and the flow of supplies they need so that there are no visible delays and there is steady measurable progress in the project as a whole. Yet, there are many moving parts overall and various small and big unexpected incidents and problems happen all the time.

To make sure that the workers...
