Netflix Inc. provided visitors and shoppers with the most bytes per second in October, according to a new performance index by Gomez Inc.
The index of the web’s 50 largest retailers as ranked by annual e-commerce sales shows that customers using a high broadband connection, low broadband connection or dial-up on average could access about 20.7 bytes of information per second from Netflix.com. Netflix was followed by Eddie Bauer (15.8 bytes), Nordstrom (9.9 bytes), Blue Nile (9.4 bytes), Peapod (8.4 bytes), Sears (7.8 bytes), Dell (7.2 bytes), Zappos (6.7 bytes), Cornerstone Brands (6.7 bytes) and Quixtar (5.8 bytes).
Measuring how many bytes per second shoppers can download using multiple connections is a key indicator of web site performance and customer satisfaction. Overall shoppers could access an average of about 3.4 bytes per second on the 50 largest retail sites, according to Gomez.
Another key indicator of site performance is measuring the average of how long it takes a customer to access a retailer’s landing page. The Gomez index, which averages the access time for high broadband, low broadband and dial-up, notes that shoppers can access BlueNile.com in a blended time of 2.4 seconds, compared to Dell (3.6 seconds), Costco (4 seconds), Cornerstone Brands (4.1 seconds), Sears (4.1 seconds), FTD (4.3 seconds), Drugstore.com (5.2 seconds), Scholastic (5.5 seconds), Zappos (5.8 seconds) and Peapod (5.8 seconds). On average visitors and shoppers could access a Top 50 retail web site in about 12.8 seconds, Gomez says.
