Page 1 of 1
Keynote Systems this week announced Keynote Perspective Full Page service, a new service for administrators of rapidly changing Web sites.
The new offering analyzes and responds to the effect of Web-page structure and content changes on the quality of service experienced by users. It measures and profiles the user's experience of downloading content from Web sites, including all images and banner ads, to multiple global locations. Site administrators can then use this data to tune their content for optimal performance using internal goals and competitive benchmarks.
In addition to download times, the service provides detailed data to aid in the diagnosis of performance problems including DNS-lookup time, connection-setup time, time to first byte, redirect time, HTML-download time, and component-download time. By using a Java-enabled Web browser, anyone can view and analyze the component performance measurements and failure rates.
Keynote Systems uses its Keynote Perspective service to measure the time needed to access and download Web pages and their components using HTTP (HyperText Transfer Protocol). The measurements are performed every 15 minutes from each of Keynotes 65 automated measurement locations around the globe.
