The Internet and Web browser-based applications have had a profound impact on how organizations distribute information, perform business processes, service customers, and reach new markets. At the heart of this is your HTTP server and Web-enabled data and applications. This IBM Redbooks publication is intended for AS/400 programmers, network and system management professionals, and other information technologists that are responsible for designing, developing, and deploying Web-based applications and information systems. You will find a holistic approach to Web server and application performance for the key components of your solution.

This book discusses such key components as:
- The Web browser client
- Network and communications infrastructure
- Application characteristics, such as static or dynamically generated Web pages
- AS/400 server processor, memory, disk storage, and communications resources

The focus is on enabling you to create a sound methodology as a continual process for sizing and planning your Web application and HTTP server environment. This includes giving you the ability to:

- Measure the right data
- Correlate application transaction events, such as Web hits, to the measured data
- Analyze resource usage and transaction times
