Scott,
The book has two chapters on Performance, one that covers Performance
testing, including setting up a test plan and running tests using the Jakarta JMeter framework. The second performance chapter deals with how to go about tuning your web application, including where to look for performance bottlenecks and general best practices.
A detailed table of contents for the book is at

Thanks,
