Network throttling in Mobile tests that run on the Backbone network

When a test is configured to use a Mobile script and run on the Backbone network, you can define the network speed the test will simulate. For example, to monitor how your website performs on a mobile device under different connection conditions, you can create tests that simulate typical 3G or 4G speeds.

For detailed and updated carrier speeds for all cities, we recommend the OpenSignal mobile app available for iOS and Android.

When you configure a Mobile test to run on the Backbone network, the test uses the Backbone test settings. For more details of creating the test, see Adding Performance tests.

You can't define the network speed when you first create the test. After it's provisioned, edit the test's advanced settings. The test must be active before you can access Advanced Settings:

If necessary, click Menu icon > Tests to display the Tests page.
Synthetic Classic Tests page

Click a test name to go to the test settings page. Or you can click the expand icon Expand icon for the test and then click Edit test.

Select the Advanced Settings tab to define the network speed.

In the Network throttling section, select Enabled.

Define the speed settings:

  • Download—The download speed in kilobytes per second
  • Upload—The upload speed in kilobytes per second
  • Latency—The latency in milliseconds

Make any other edits you need, then click Update and Finish to close the test editing page.

Important

The throttling settings apply for all nodes. If you create a test on 10 nodes and throttle the network to simulate Vodafone in London, all 10 nodes, regardless of location, will mimic those settings.

To have a different throttling settings for each node, you must set up multiple single-node tests.
