Dell.com had the best Internet Explorer consistency score among large retailers for September, says Gomez, the web performance division of Compuware Corp. Last month, the retailer had the best site loading time with a variation, or score, of 0.65 seconds, which means the Dell web site loaded within 0.65 seconds of its average load speed when successfully tested.

Rounding out the top five retailers in Internet Explorer testing after Dell.com, Gomez listed LLBean.com (0.69 seconds), OfficeDepot.com (0.72 seconds), Walmart.com (1.04) and Overstock.com (1.08).

QVC.com had the best Firefox consistency score in September with an average of 0.55 seconds, Gomez reports. Costco came in second (0.71 seconds) followed by Dell.com (0.78), Williams-Sonoma.com (0.89) and LLBean.com (0.95).

Of the 20 retailers measured in September, the average Internet Explorer consistency score was 1.35 seconds. The same 20 retailers produced an average Firefox consistency score of 1.34 seconds.

The consistency ratings take into account differences in the speed of web page delivery across multiple visits.

Imad Mouline, chief technology officer at Gomez, will be speaking at the Internet Retailer Web Design & Usability Conference Feb. 14-16, 2011 in Orlando, FL, in a session titled What you don't know about today's browsers can hurt you.
