What does Fast 3G actually mean? : <p>In the Chrome browser's developer tools, there are various ways to throttle your network connection to emulate different connection types.</p>

<p>Those menus for selecting a connection type used to show the speeds and latency that would be used to simulate each connection type.<br>

<p>Now, as of at least Chrome 64, the useful information about speed and latency has been removed.<br>

<p>I tried duplicating the numbers from the first image for Regular 3G and Good 3G in my own custom profiles to see if they matched the Slow 3G and Fast 3G presets from the first image but I got significantly different results for the DOMContentLoaded and Load event times between the presets and my custom profiles.</p>
