Introduction to the Networks Tab in Chrome Developer Tools

The networks tab in the Chrome developer tools panel can provide rich insights.  It allows you to see what resources are being loaded, how many HTTP requests are being made, which scripts are blocking the page load, how long it takes for assets to load, how long it takes for the page to load, when the DOM is ready, if there are any 404 status codes, and much, much more.

To take advantage of the network panel in Chrome developer tools, just open up the developers tools by right clicking any element on the page and clicking ‘Inspect Element’ or by going to the ‘View’ menu bar item, selecting ‘Developer’, then clicking on ‘Developer Tools’.  Next, make sure to select the ‘Network’ tab and reload the page to ensure you get a full dataset.
