Java Performance Tuning

by Jack Shirazi

Performance has been an important issue for Java developers ever since the first version hit the streets. Over the years, Java performance has improved dramatically, but tuning is essential to get the best results, especially for J2EE applications. You can never have code that runs too fast. 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 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. Java Performance Tuning , Second Edition shows you how Covers JDK 1.4

Too many people think that there is no need to care about performance because the JVM optimizes the code automatically. That's why there are tons of highly inefficient code. Sometimes, a very simple change can make your code run hundreds or thousands of times faster, saving costs, improving responsiveness. This book is a must read for every Java programmer.

I certainly learned a lot about writing faster java code although light on advanced garbage collection techniques. Honestly, learning how to use the garbage collector better did more for the speed of my java code than most of the tricks I learned in here.

Every Java coder should have read this. There are too many idiot coders out there. Some of the performance proposals should probably be stayed away from, though... Overall, a good book to teach you some "performance manners"...

Very good to understand that main improvement in software, even in java can be done on our code side.
The VM isn't an excuse after reading this book

There is a lot out of date but still a lot of good facts that still hold
