QVC’s mobile site posted the best response times across four carriers and devices.
QVC’s mobile site, m.QVC.com, produced the fastest iPhone access time among large web retailers in May, says Compuware Gomez. Last month, m.QVC.com produced an average iPhone mobile response time of 1.45 seconds.
M.Newegg.com came in second for iPhone testing with 2.03 seconds, followed by Amazon.com (3.23 seconds), Williams-Sonoma.com (3.39) and Dell.com (3.62).
QVC’s mobile commerce site also led in response time tests for the three other mobile devices measured by Gomez in May: Sprint’s HTC Hero (1.61 seconds), T-Mobile’s HTC Dream (3.86 seconds) and Verizon’s Droid (1.85 seconds). Amazon’s mobile site finished second in testing for the HTC Hero and the Droid.
Gomez measures response time as the end-to-end time elapsed while downloading each mobile site.
