Dell Inc. jumped three positions on this week’s Keynote Mobile Commerce Performance Index to take the No. 1 spot, unseating StrandBooks.com and Walmart.com, both of which have alternated in the No. 1 spot for the most part for some time. Dell achieved a score of 968 out of 1,000, its m-commerce site home page downloading on average in 4.11 seconds, doing so successfully 99.01% of the time. The measurements are for the week ending Feb. 11.
StrandBooks.com came in second, dropping one position, with a score of 966. Its mobile home page downloaded in 3.87 seconds and did so successfully 98.40% of the time. Walmart.com dropped three positions with a score of 856. Its mobile home page downloaded on average in 4.89 seconds and did so successfully 98.81% of the time.
“These are Dell’s best load time and reliability ever since the index started running,” says Herman Ng, mobile performance evangelist at Keynote Systems Inc. “Compared to its data four months ago, Dell’s mobile site load time has improved by 2.63 seconds and reliability by 1.82 percentage points. Looking back at Dell’s historical data, we noticed a major change in its load time trend since Nov. 1—instead of an upward degrading load time trend, the trend did a 180 and started a positive downward trend, which led to Dell’s greatest performance last week, and provided their end users with an amazing experience.”
The index average score was 749, with an average m-commerce site home page download time of 5.40 seconds and a success rate of 98.07%. The index was up 168 points from the previous week.

Mobile and web performance management firm Keynote Systems measures 15 representative m-commerce sites exclusively for Internet Retailer. The sites include merchants in various categories and channels, and of various sizes, ranging from such giants as Sears Holdings Corp. and Foot Locker Inc. to midsized retailers like Sunglass Hut and K&L Wine Merchants. Keynote repeatedly tests the sites in the index Monday through Friday from 8 a.m. through midnight Eastern time, emulating three different smartphones on three different wireless networks: Apple Inc.’s iPhone on AT&T, the BlackBerry Curve on Sprint and the Droid (which uses Google Inc.’s Android operating system) on Verizon.
Keynote combines a site’s load time and success rate, equally weighted, into a single score. Given both performance and availability are important, the score reflects the overall quality of the home page; a higher score indicates better performance. Scores also reflect how close sites are to each other in overall quality. The index average score is the midpoint among all the sites’ scores.
