How well a Web site performs while receiving heavy user traffic is an essential factor in an organization's overall success. How can you be sure your site will hold up under pressure?

Performance Analysis for Java(TM) Web Sites is an information-packed guide to maximizing the performance of Java-based Web sites. It approaches these sites as systems, and considers how the various components involved, such as networks, Java(TM) Virtual Machines, and backend systems, potentially impact overall performance. This book provides detailed best practices for designing and developing high-performance Java Web applications, and instructions for building and executing relevant performance tests to gauge your site's ability to handle customer traffic. Also included is information on how to use the results of performance testing to generate accurate capacity plans.

Readers will find easy-to-understand explanations of fundamental performance principles and terminology. The book runs through performance profiles for common types of Web sites, including e-commerce, B2B, financial, and information exchange. Numerous case studies illustrate important ideas and techniques. Practical throughout, the book also offers a discussion on selecting the right test tools and troubleshooting common bottlenecks frequently revealed by testing.
