Java Performance Tuning, Second Edition By Jack Shirazi Also you can...
Recently I happen to read the Orielly J2ME In A Nutshell book. Even though it is a book on J2ME, I found most of the programming practices followed and described in the book could be used on any other Java edition. These practices avoid unnecessary processing burdon and memory consumption hence resulting better performance.
Now I find myself following most of these practices on my regular developments. You also can give it a try if you have spare time to read material relaing to different field.
