Java 9 High Performance

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 new G1 collector

The Java community is keen and excited about the Java 9 and its related packages and primary features. Garbage collection is an important Java function, and therefore, it is essential to discuss the new G1 collector that is being promoted in the new package. This takes away from the direction of the previous method of ParallelGC. We will refer to the new collector as the Garbage First Garbage Collector (G1GC) throughout the article.

It is a multithread-capable GC tool and has the ability to work concurrently on different processing threads. The G1GC collector is designed to work with application threads and reduce the pause times, which appear with the use of a garbage collection method.

G1GC is entirely different in terms of creating heap divisions. It does not create three big piles of heap. It creates a number of equal-sized heaps, which can work together...
