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.
