The world of Java performance has shifted significantly in the past ten years. Multicore machines and 64-bit operating systems are now standard even for casual users, and Java itself has introduced new features to manage applications. The base JVM has kept pace with those developments and offers a very different performance profile in its current versions. By guiding you through this changing landscape, Java Performance: The Definitive Guide helps you gain the best performance from your Java applications.
You´ll explore JVM features that traditionally affected performance-including the just-in-time compiler, garbage collection, and language features-before diving in to aspects of Java 7 and 8 designed for maximum performance in today's applications. You´ll learn features such as the G1 garbage collector to maximize your application´s throughput without causing it to pause, and the Java Flight Recorder, which enables you to see application performance details without the need for separate, specialized profiling tools.
Whether you´re new to Java and need to understand the basics of tuning the JVM, or a seasoned developer looking to eek out that last 10% of application performance, this is the book you want.
