The network tab in Chrome DevTools has an option to throttle your network speeds, network throttling allows you to test your site on a variety of network connections, including Edge, 3G, and even offline.
Besides the obvious, it’s also useful for visualizing how your website loads on different network connections.
- Open DevTools (CTRL + SHIFT + I)
- Click the ‘Network’ tab
- Select which type of connection you want to imitate
- Reload the page to see assets downloading at that connection speed
If the standard options aren’t to your liking, you can even make a custom network throttling profile by clicking the option at the very top of the dropdown menu.
