Web Performance Matters

This paper presents a framework that describes all the components that make up the response time of an e-commerce application. Understanding this fundamental framework is the key to implementing responsive e-commerce systems.

The paper discusses examples of how e-commerce application response times can be improved in three ways: by reducing the overall number of components, by speeding up individual components, and by moving some components off the synchronous response time path.

Many Internet users need to understand how to measure Internet traffic and performance. The primary focus of this tutorial is the global Internet, and ways of measuring, analyzing, and reporting the services provided to a user's network via the Internet. Some sections apply to measuring any network that uses the TCP/IP protocol suite, including a private network, or intranet.

Statistical analysis of Web page download time measurements suggests that some relatively simple formulae can be derived to project page download times based on Web page composition and TCP connect time for a browser/server pair.

The Web page response times experienced by users are affected by six principal variables: page size, minimum bandwidth, number of turns, round-trip time, server processing time, and client processing time. The paper explains these variables and their influence, and presents a formula correlating them with response time.
