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.

Understanding the Java 9 garbage collector for top optimization

Garbage collection is an important technique used for automatic reallocation of memory. The new JDK 9 is a project that requires implementation of the Java SE 9 platform. It is defined in the Java community as the JSR 379 process and serves as the key to implementing the JEP 2.0 proposal.

One of the important ideas is to find the ideal and the most optimized method for memory allocation. We will discuss different garbage collector algorithms in this article. The important and proven technique of Parallel GC will be explained here as well while discussing concepts such as parallelism, heap sizing, and G1 collector facilities.

Different failures will also be discussed here, and then, further details of the new garbage collection mechanism will be explained.
