Browser benchmark test7/30/2023 Note: The source for this demo is at MicrosoftEdge / Demos > devtools-performance-get-started. For more information about InPrivate, see Browse InPrivate in Microsoft Edge You'll profile this page, which shows a variable number of icons moving up and down. To do that, right-click the link and then select Open link in InPrivate window. Open the Sluggish Animation demo page in your InPrivate tab or window. In the following tutorial, you open DevTools on a "Sluggish Animation" demo page and use the Performance tool to find a performance bottleneck on the page. See also Optimize website speed using Lighthouse. In terms of the RAIL model, the skills you learn in this tutorial are useful for analyzing the Response, Animation, and Idle phases of your page. The following tutorial teaches you how to use the DevTools Performance tool to analyze runtime performance. For example, if you have three items, choosing Distribute sets the percentage values to 34, 33, and 33.Runtime performance is how your page performs when it's running, as opposed to loading. The Distribute button is used to allocate the percentage values equally among all items. Then, when you move a slider, the amount you add or remove is only applied to any remaining unlocked items. If you select the check box in the lock column for a particular item, you lock the specified percentage value for that item. It is possible to override this behavior. If you have more than two items, the amount you add or remove is distributed evenly among the other items. When you move a slider, the percentage values of all available items change. Adjusting the mix for the browser types specifies the probability of a virtual user running a specific browser type in a load test scenario. You adjust the percentage values by moving sliders. The mix control allows you to adjust the percentage of load that is distributed among tests, browser types, or network types in a load test scenario. When you are finished removing browsers, choose OK. Select the browser in the grid and then choose Remove. The Edit Browser Mix dialog box is displayed. Right-click the scenario from which you want to remove a browser and then choose Edit Browser Mix. Remove browsers from a scenario To remove browsers from a scenario When you are finished adding browsers, choose OK. (Optional) Adjust the mix control to specify the test distribution. In the Browser Type column, choose the arrow for the new entry and choose the desired browser type. To display the Edit Browser Mix dialog box, right-click an existing scenario and then choose Edit Browser Mix. ![]() The mix control lets you easily adjust the distribution of browsers in a scenario. You can also change the distribution of the browser mix by using the mix control. The tests of that user are run on a particular web browser, based on the probability that you specified in the mix.Īfter you have specified a browser mix, you can later add and remove web browser types to the mix. A web browser type is randomly associated with a virtual user, based on the browser mix. The browser mix works like other mix options. When you add a web browser type to the mix from the set of web browsers that are provided, a set of associated headers for the selected web browser is added to each HTTP request that is submitted by a web performance test. When you create a load test, you might want to simulate that the load is generated through more than one web browser. You create a closer approximation of the web browsers that will be used with your applications.Ī browser mix specifies the probability of a virtual user running a particular web browser type in a load test scenario. Load is generated by using a heterogeneous mix of web browsers instead of one single web browser. The browser mix gives you a way to simulate load more realistically in a load test scenario.
