Riassunto:

Performance tuning is an experimental science, but that doesn’t mean engineers should resort to guesswork and folklore to get the job done. Yet that’s often the case. With this practical book, intermediate to advanced Java technologists working with complex technology stacks will learn how to tune Java applications for performance using a quantitative, verifiable approach.

Most resources on performance tend to discuss the theory and internals of Java virtual machines, but this book focuses on the practicalities of performance tuning by examining a wide range of aspects. There are no simple recipes, tips and tricks, or algorithms to learn. Performance tuning is a process of defining and determining desired outcomes. And it requires diligence.

• Learn how Java principles and technology make the best use of modern hardware and operating systems
• Explore several performance tests and common anti-patterns that can vex your team
• Understand the pitfalls of measuring Java performance numbers and the drawbacks of microbenchmarking
• Dive into JVM garbage collection logging, monitoring, tuning, and tools
• Explore JIT compilation and Java language performance techniques
• Learn performance aspects of the Java Collections API and get an overview of Java concurrency

He is a Java Champion; JavaOne Rockstar; co-author of “The Well-Grounded Java Developer” and a regular public speaker on the Java platform, performance, concurrency, and related topics.

James (Jim) Gough is a Java developer and author. Jim first became interested in Java during his degree program at the University of Warwick, and after graduating he became a member of the London Java Community. Community has remained central to Jim’s contributions, which include working on the design and testing of JSR-310 and serving on the Java Community Process Executive Committee for several years. Jim is a regular conference speaker and is currently focused on building customer facing technology at Morgan Stanley. He spent four years teaching Java and C++ in various countries around the world.

Chris Newland has been working with Java since 1999 when he started his career using the language to implement intelligent agent systems. He is now a senior developer and team lead at ADVFN using Java to process stock market data in real time. Chris is the inventor of JITWatch (https://github.com/AdoptOpenJDK/jitwatch), an open-source visualiser for understanding the Just-In-Time (JIT) compilation decisions made by the HotSpot JVM.
