Performance tuning is an experimental science, but that doesn't mean engineers have to resort to guesswork and folklore to get the job done (though that's often what happens). With this practical book, mid- to advanced-skilled developers working with complex technology stacks will learn how to tune high-performance Java applications using a quantitative, verifiable approach.

Performance is typically discussed in most information resources. theory and the inner workings of Java virtual machines, but this book focuses on practical performance tuning by exploring a wide range of aspects. There are no simple recipes, tips and tricks, or algorithms in the book. Performance tuning is a diligent process of making changes and measuring the results.
