Description

This book will discuss the problem of Capacity Planning and Performance Analysis in Web Server, Inranet and Client/Server environments. It’s going to identify problem areas where capacity planning and performance analysis are critical concerns: arrival rate, through-put, response time, service demand, workload, delay, bottleneck, and saturation. It’s going to discuss protocol (HTTP & TCP/IP) and workloads (access to HTML documents, graphics, etc.). It’s going to show how to access existing capacities and how to plan for future capacities. It’s going to discuss benchmarking metrics, global systems problems, workload forecasting, etc.
Given your server hardware and Internet connection, how many users can your Web site handle? Capacity Planning for Web Performance can show you the techniques for estimating and planning effectively for your Web site’s workload, both for today and the next day to come. This textbook-style remedy of the topic presents concepts and formulas for making sure your Web infrastructure is up to the task.

In early sections of this book, the authors introduce the basic concepts of capacity planning and probably the most Web-specific issues that you will have to overcome for effective planning. (For instance, Web traffic is “bursty”–as any Webmaster will attest–and can fluctuate greatly.) Short chapters on system architectures, from traditional client servers to today’s Web-centered thin clients, are discussed, as are the basics of TCP/IP and HTTP.

Subsequent sections discuss how to measure performance on your system, the usage of tools such as Web benchmarks, and how to provide formulas for estimating how much hardware is required for “acceptable” performance.

All the way through Capacity Planning for Web Performance, there’s a fair amount of mathematical detail. Though there are many real-world examples, this is not a guide to just tweaking Web servers; this can be a highly technical guide to state of the art thinking on issues of measuring performance on the Internet. Applying metrics to Web performance can benefit any Web-minded business, though It’s going to probably take the technically savvy reader to effectively execute this knowledge. –Richard Dragan
