<pre>Author/s : Jack Shirazi Publisher : O'Reilly Category :Advanced Java Review by : Thomas Paul Rating : 9 horseshoes</pre> Once the business rules have been settled and all that is left is to tune the code, then the fun starts. Like a race car mechanic trying to squeeze out a couple of extra MPH from a race car, the most fun in programming is to try squeeze out extra performance from some code. A book on performance tuning should understand that and make the topic fun. Reading this book it is clear that Jack Shirazi loves to tune code. He has done an incredible amount of detailed research on different JVMs to determine exactly how to make Java perform. But he is also practical. He explains how to find performance problems, which exact areas to concentrate on, and which areas to ignore. After reading this book you won't waste your time on areas of code that can't be easily optimized and instead you'll know how to concentrate on those places where you can get the most bang. The book has been updated from the earlier edition to bring all the information up to date with the latest JVMs. Best of all, an additional 250 pages has been added to the book covering J2EE including Servlets, JSPs, EJBs, and JDBC. "Java Performance Tuning" is a programmer's book. You are guaranteed to learn a lot of very neat and useful tricks. I doubt that there is another Java book on the market with as many "WOW!" moments in it. Buy it and watch your code zoom.
