Bloomingdale's too bloated for good mobile performance, Keynote says

There also is a problem when it comes to how the m-commerce site home page loads on feature phones. Keynote measures performance on four devices: three smartphones and one feature phone. The average load time on the feature phone for the week ending Feb. 5 was a mind-boggling 81.92 seconds.

“Bloomingdale’s has a well-designed mobile page when it comes to the graphic look,” Ng says. “While feature phones are getting smarter and are capable of handling complex HTML pages, it still takes longer to download the same page from a feature phone compared to a smartphone. Therefore, Bloomingdale’s can optimize its mobile page further for feature phone devices, which will improve load time and ultimately improve the overall user experience.”

In addition to the 20.91-second load time, Bloomingdale’s average success rate—the percentage of the time a page loads completely and successfully—was 97.20%. Its load time and success rate combined and weighted earned it a score of 482 out of 1,000. The index average success rate was 97.12% and the average score was 781.
