Page 1 of 1
Despite some highly-publicized failures, the leading online shopping Web sites serviced holiday shoppers with performance and availability rates better than the industry-average business Web site, according to a study by Keynote Systems.
On Dec. 17, for example, Amazon.com delivered its home page in an average of 4.9 seconds with an availability rate of 99.4 percent compared to an industry average of 9.2 seconds and 97.5 percent. The study was based on over 800,000 measurements.
Sites studied included Amazon.com, Barnes & Noble, Dell, Gateway, Lands' End, Virtual Vineyards and the industry-standard Keynote Business 40 Index. The results of the study, including several performance graphs and availability tables from the week of December 14, are available here.
Performance and availability rates from Dec. 17 are:
- Amazon.com - 4.9 seconds, 99.4%
- Barnes & Noble - 7.3 seconds, 99.2%
- Dell - 8.3 seconds, 99.1%
- Gateway - 6.4 seconds, 86.7%
- Lands' End - 9.0 seconds, 91.5%
- Virtual Vineyards - 4.9 seconds, 96.7%
- Keynote Business 40 Index - 9.2 seconds, 97.5%
"With e-commerce on the Web, performance and availability are crucial factors in retaining and satisfying online customers," said Umang Gupta, chairman and CEO of Keynote Systems. "This study as well as our Web Brokerage Index and Keynote Business 40 Index scientifically measure and report these quality of service factors to the public for the most important e-commerce activities on the Internet today."
Keynote Systems uses its Keynote Perspective Full Page Component service to measure how long it takes to access and download Web pages and their components via the Microsoft and Netscape browsers. The measurements are performed every 15 minutes around the clock from each of Keynote's 65 automated measurement locations around the world.
Availability rates reflect all failures to download a Web page or any of its components because of web-server or Internet errors.
