Amazon.com Review 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 tomorrow. This textbook-style treatment 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 some of the Web-specific issues that you must 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, using tools such as Web benchmarks, and how to provide formulas for estimating how much hardware is required for 'acceptable' performance. Throughout Capacity Planning for Web Performance, there's a fair amount of mathematical detail.

Though there are plenty of real-world examples, this is not a guide to just tweaking Web servers; this is 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 will probably take the technically savvy reader to effectively execute this knowledge. --Richard Dragan.

Product Description This book will discuss the problem of Capacity Planning and Performance Analysis in Web Server, Inranet and Client/Server environments. It will 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 will discuss protocol (HTTP & TCP/IP) and workloads (access to HTML documents, graphics, etc.). It will show how to access existing capacities and how to plan for future capacities. It will discuss benchmarking metrics, global systems problems, workload forecasting, etc.

If you thought Web architectures were too complex for modeling, you are wrong! This text explains all possible major components of Web transactions - from TCP/IP, http, CGI, proxy and cache servers, browsers, and networks, in detail. It also explains and adapts various utilization, queue, and response time models to performance analysis and capacity projections. This text is outstanding as both a tutorial and reference. Particularly useful are many real world examples with solutions based on the models. The models are available as Excel worksheets.
