Amazon’s mobile site produced the fastest iPhone access time across all service providers among large web retailers in March, says Compuware Gomez. Last month, Amazon.com produced an average iPhone mobile response time of 2.94 seconds.
M.Sears.com came in second for iPhone testing with an average of 3.39 seconds, followed by OfficeDepot.com (3.76 seconds), LLBean.com (4.70) and Dell.com (5.01).
Gomez measures the average iPhone response time for three major wirelessservice carriers: AT&T, Sprint and Verizon. Testing for all 20 retailers takes place once per hour per carrier from two U.S. locations (Virginia and California).
Gomez measures response time as the end-to-end time elapsed while downloading each mobile site.
