PAGE ANALYZER: A TOOL FOR WEB PERFORMANCE MODELING

Web page retrieval time depends on many factors. Measuring total retrieval time only shows if and when a problem exists, not where or why. Tools providing detailed breakdowns of page retrieval activities help to highlight performance problems. By modeling these activities under different assumptions, we have built tools to analyze and predict performance. By comparing the "as-is" and "what-if" performance results, we can assess the effects of various changes to web content design and deployment, making informed, cost effective decisions resulting in improved customer browsing experience.
