How to test slow network speed in Chrome ?

No, this post is not just about salesforce 🙂 , it’s about “How to test slow network speed in Chrome ?”

Have you been into situations when you wanted to test your web application in a slow network ? Here is a quick trick to test webapps in slow network connections. I know may are very fortunate to have high speed internet, so why to test web applications in slow network… Some times we wanted to have wait statements to see how it works if there is a slow network which is accessing your web application.

There is a setting in Chrome which can simulate the network speed :

1. open the web app you want to test in slow network or variety of network modes
2. Once the application is open click on F12(Windows) to get the developer tools enabled. Your browser screen should look like something as below screenshot:

3. 

4. Now you can see the network options in the screen, you can select any speed you want to simulate or even you can create your custom speed.

Conclusion:

When you will need this ? Good question… When we have broad band and fiber network at our reach why to worry about slow networks… Some time it’s good to test your code performance on a slower network. Everyone is not lucky enough yet to get high speed internet. Also some time you may have a code block that runs a please wait symbol, but due to high internet speed you might not test how it looks. At that time you may want to use this feature.

So, I have not tested or used other browsers much so not aware if they are available or not.
