Introduction -- An approach to performance testing -- A Java performance toolbox -- Working with the JIT compiler -- An introduction to Garbage collection -- Garbage collection algorithms -- Heap memory best practices -- Native memory best practices -- Threading and synchronization performance -- Java servers -- Database performance best practices -- Java SE API tips -- Appendix A: Summary of tuning flags

Coding and testing are generally considered separate areas of expertise. In this practical book, Java expert Scott Oaks takes the approach that anyone who works with Java should be adept at understanding how code behaves in the Java Virtual Machine-- including the turnings likely to help performance. This updated second edition helps you gain in-depth knowledge of Java application performance using both the JVM and the Java platform. Developers and performance engineers alike will learn a variety of features, tools, and processes for improving the way the Java 8 and 11 LTS releases perform. While the emphasis is on production-supported releases and features, this book also features previews of exciting new technologies such as ahead-of-time compilation and experimental garbage collections
