The maker of software for online retailers processed more than $1.6 billion in orders in the quarter.
The mass merchant had the best aggregate site loading time at 17.60 seconds.
Overstock.com had the best consistency rating among large retailers for May, says Gomez, the web performance division of Compuware Corp. Last month the mass merchant had the best aggregate site loading time at 17.60 seconds.
Rounding out the top five retailers after Overstock.com, Gomez listed CDW.com (17.85 seconds), Staples.com (18.75), LLBean.com (18.93), and BlueNile.com (18.99).
In May, 26 of the 48 major retailers tested topped the group’s average consistency score of 23.95 seconds.
The consistency ratings take into account differences in the speed of web page delivery across multiple visits. The lower the total consistency time, the less variation there is in page loading times across the study period.
