erformance tuning is an experimental science, but that doesn mean engineers should resort to guesswork and folklore to get the job done. Yet that 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.ost 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.earn how Java principles and technology make the best use of modern hardware and operating systemsxplore several performance tests and common anti-patterns that can vex your teamnderstand the pitfalls of measuring Java performance numbers and the drawbacks of microbenchmarkingive into JVM garbage collection logging, monitoring, tuning and toolsxplore JIT compilation and Java language performance techniquesearn performance aspects of the Java Collections API and get an overview of Java concurrency
