Fast web pages are critical to a good user experience, but what is “response time” and how should it be measured? This panel discusses what parts of page loading should be measured and the importance of perceived versus instrumented speed. Frameworks for measuring response time are compared: services (such as Keynote, Gomez, and WebMetrics), home grown test labs, and instrumenting real user traffic. The challenges of, and possible solutions to, measuring Web 2.0 applications are discussed.
