The retailer led web site consistency tests for Internet Explorer and Firefox.
Dell.com had the best Internet Explorer consistency score among large retailers tested in August, says Compuware Gomez. Last month, the retailer had the most consistent site loading time with a variation of 0.51 seconds. Apple.com (0.83 seconds), placed second in Internet Explorer tests, followed by Gap.com (0.85) and Walmart.com (0.93). OfficeDepot.com and Overstock.com tied for fifth place at 1.02 seconds.
Dell.com also posted the best Firefox consistency score in August, Compuware Gomez reports, with an average variation of 0.78 seconds. Apple.com and QVC.com (1.02 seconds) tied for second place. Overstock.com (1.05) came in third while Gap.com and Costoc.com (1.09) tied for fourth.
The average Internet Explorer consistency variation among the 19 retailers measured in August was 1.54 seconds. The same group of retailers produced an average Firefox variation of 1.80 seconds.
The consistency ratings take into account differences in the speed of web page delivery across multiple visits.
