Chrome can be used to simulate a slow connection.
Install Chrome if it is not already installed on your system. After that, open a new tab and press CTRL + SHIFT + I to bring up the developer tools window, or click on the hamburger icon, then More tools, then Developer tools.
Now click on Network section – a drop-down menu of pre-configured speeds appears, which you can use to simulate a slow connection.
To add your own custom values, click the Add button under Custom. To create a new profile, click the Add Custom Profile button.
This is an excellent tool that is integrated into Chrome that you can use to determine the load time of your website on slower connections. Please feel free to leave a comment if you have any questions. Enjoy!
