Stress Testing Load on a Server Everyone is talking about the need to "load test" their servers--whether Web servers or proprietary server software--but how do the people who must load test these servers actually perform the testing? Learn how different companies load test their servers by simulating thousands of connections using a combination of publicly available tools and proprietary utilities.

Performance Testing E-Commerce Web Systems Performance testing of e-commerce Web systems is critical to the effectiveness of Web sites. Michael Hagen describes how Vanguard went through extensive load testing in preparation for the Y2K weekend. Discover how to develop performance requirements, set up a performance testing environment, and execute the actual testing. Gain invaluable insight into what makes a Web system--from browser to mainframe-perform or not perform.

The Science and Art of Web Site Load Testing The magnitude and unpredictability of Internet loads pose unique testing challenges for Web sites. The only sure way to know how a Web site will behave under a heavy user load is to perform a load test. In this presentation, learn the core principles and techniques necessary for highly realistic and revealing Web site load tests. Listen to several case studies that illustrate why Web sites cannot afford to ignore load testing.

Performance Evaluation and Measurement of Enterprise Applications Today's large-scale enterprise applications are all Web-enabled and complex in nature. Many users experience performance problems from day one. Performance evaluation and measurement via extensive testing is the only practical way to raise and address all issues prior to a successful deployment. Learn how to tackle performance and capacity issues with the appropriate testing strategy and scalable infrastructure/architecture.

Tuning Application Performance in Production Even applications that have gone through rigorous testing in QA tend to have serious performance problems in production. Nearly every CIO or production manager has horror stories of applications that went live and failed. Yet with so much on the line, why are we in a constant firefighting mode? When confronted with new problems, we have to start with the basics and ask, "Is the problem in the application or in the infrastructure? How can I narrow it down fast?" Production tuning takes your good QA practices to the next level, and helps you get out of firefighting mode.

STAREAST 2002: A Case Study In Automating Web Performance Testing Key ideas from this presentation include: define meaningful performance requirements; changing your site (hardware or software) invalidates all previous predictors; reduce the number of scripts through equivalence classes; don't underestimate the hardware
needed to simulate the load; evaluate and improve your skills, knowledge, tools, and outsourced services; document your process and results so that others may learn from your work; use your new knowledge to improve your site's performance and focus on progress, not perfection.

Get Real ! The Importance of Realism for Web Site Capacity Assessment What is meant by Internet realism during load testing/capacity assessment? Part of it is understanding the importance of not only carefully characterizing the behavior of visitors to a Web site, but also the behavior of the Internet itself. Contributing to this realism are important measures such as packet loss, link speeds, millions of IP addresses, browser emulation, SSL, and other factors that can cause significant performance issues. The Internet has all these issues, and testing with these values is an important part of gaining a clear picture of system performance right from the start. Philip Joung shows you the different factors and how each one can have a significant impact on your site's performance.

Web Log Analysis for Performance Troubleshooting Web server logs contain powerful-but often hidden-information about the performance of your Web application. In this session, you'll learn how easy it is to enlarge your toolkit for Web performance testing. For instance, Web Performance Log Analysis is a new activity that's based on performance information of Web server logs (elapsed time, bandwidth, number of hits, and more). Giuseppe Cassone shows you all the information you can extract from the log (with a focus on performance) and how you can best use it.
