"Don't lower your expectations to meet your performance.
Raise your level of performance to meet your expectations."
As its title imply "Java Performance: The Definitive Guide - Getting the Most Out of Your Code" covers Java Performance at large.
Performance analysis is about about observing and understanding what an application is doing so the book continues with an ideal Java Performance Toolbox. It covers some of the tools available to monitor Java applications. It should be mentioned that Java Mission Control that has been recently added to Java SE 7 (starting with update 40) and Java SE 8 is also discussed.
The book then dive into Java performance by discussing in great details two key fundaments that are the JIT (Just-In-Time) compiler and the Garbage Collection.
The remaining chapters focus on best practice uses of various parts of the Java platform. It's the platform at large as it goes from memory use with the Java heap, native memory use, thread performance to Java EE, JPA and JDBC!
