JVM Performance Engineering: Inside the OpenJDK Hotspot VM teaches experienced programmers how to tap Java's extensive API, automatic memory management and tools such as the micro benchmarking harness, and to develop their applications while being platform agnostic. Featuring sample code that reflects real-world use cases, this practical book by JavaOne Rockstar Monica Beckwith explains the key features and functions of the JVM. JVM Performance Engineering covers managed runtimes concepts such as just-in-time compilation (JIT), ahead-of-time compilation (AOT), and memory management. It examines these concepts from a performance perspective and classifies their impact on throughput, startup, footprint and responsiveness and benchmarking considerations. For more seasoned Java programmers, this book provides a detailed understanding of the newer concepts introduced since Java SE9, focusing on their possible performance considerations. Beckwith shows how Java's new module system (Project Jigsaw) enables working developers to build scalable solutions that are more secure and maintainable; and deliver exceptional performance. She reviews Java SE 9 changes in areas ranging from data types to performance optimizations; showing how to make the most of Java's new tools and facilities. You will learn about OpenJDK's Java 11 LTS (Long Term Support) update and enhancements coming in OpenJDK Java 15 such as its newer garbage collectors, its logging framework, and micro-benchmarking harness (aka JMH). You'll learn how to: Create microbenchmarks using the microbenchmarking harness Create a modular jar Take advantage of Java's new logging interface Take full advantage of the new default GC (garbage collection) Use sjavac, segmented code caches, and contended object monitors Create, compile and profile simple applications using the Netbeans IDE, and Oracle Developer Studio Performance Analyzer and much more If you're serious about performance engineering--or want to know why you…
