Mobile Web
We monitored the web performance of the IR50 websites (Excluding Grainger, McMaster-Carr and Symantec ) from 16 4G Nodes in NY, Atlanta, Los Angeles, Chicago DC, San Francisco, Dallas & Denver on both ATT & Verizon using an Iphone 5 (emulation). The goal was to compare the performance of the sites and to see how well each website handled the traffic during the event. Web sites that did not have a mobile web site version were slower.
Sample size: 1500 test runs per site.
Very impressed by the uptime of some of the mobile sites this year:
Metrics Calculation: Metrics display median value.
Document Complete: The time it takes the browser to download and render the page. This is the time when the browser states “Done” in the status bar – or the mouse changes from “Waiting” state to a pointer.
Render Start Time: The time it takes for the page to start displaying something other than white space.
