%0 Journal Article %T Performance and Scalability Models for a Hypergrowth e-Commerce Web Site %A Neil J. Gunther %J Computer Science %D 2000 %I arXiv %X The performance of successful Web-based e-commerce services has all the allure of a roller-coaster ride: accelerated fiscal growth combined with the ever-present danger of running out of server capacity. This chapter presents a case study based on the author's own capacity planning engagement with one of the hottest e-commerce Web sites in the world. Several spreadsheet techniques are presented for forecasting both short-term and long-term trends in the consumption of server capacity. Two new performance metrics are introduced for site planning and procurement: the effective demand, and the doubling period. %U http://arxiv.org/abs/cs/0012022v1
