Java Peformance Tuning, 2nd edition provides a comprehensive and indispensable guide to eliminating all types of performance problems. Using many real-life examples to work through the tuning process in detail, JPT shows how tricks such as minimizing object creation and replacing strings with arrays can really pay off in improving your code's performance. Tuning J2EE applications bears many similarities to tuning J2SE apps, but important and specific considerations apply. For this reason,
Java Performance Tuning, Second Edition includes four new chapters: a new chapter on J2EE application tuning in general followed by chapters on tuning JDBC, servlets and JSPs, and EJBs.
Java Performance Tuning offers common-sense advice about what to tune and what to leave alone, emphasizing techniques that provide big performance gains with minimal code restructuring. It gives you crucial guidance that helps you tune without destroying your program's architecture. Blindly changing things in an effort to make a program run faster is a great way to create buggy, unmaintainable code.
Java Performance Tuning teaches you to work efficiently and effectively, resulting in code that is robust, maintainable, and fast.
Customer Reviews & Comments
The book ranges rather widely, covering a huge number of tuning details. The author seems to know hands-on performance tuning very well, and many of the examples were directly applicable to our own development. There is only one chapter on designing for performance (I would have liked more), but in that chapter he did identify precisely the issues that we encountered in our project. The example of double sorting internationalized text transferred directly to our project and speeded up a crucial area of our presentation. I do recommend this book, but do not expect a design book. This is strongly hands-on performance tuning.
