Description WebPageTestWebPageTest is a free platform designed primarily to help developers test the performance of the websites they are responsible for.
What is WebPageTest?Recently redesigned, WebPageTest is a platform with several very practical features to effectively test the performance of a website. WebPageTest also receives very good and quite laudatory comments. The platform is often considered the best in terms of features and options for testing a website. One of the popular features on WebPageTest is the ability to run performance tests from multiple geographies using real browsers with real connection throughput. Unlike the scores offered by other tools to evaluate the performance of a website, this feature of WebPageTest allows you to test your site using the position of your users exactly as if you were there. You could then get a concrete snapshot of loading speed, exactly as it appears on your users’ devices, with actual location and connection. WebPageTest also allows you to perform other types of tests, including simple and advanced tests, Total Blocking time (TBT), traceroute tests, Core Web Vitals, multisite visual comparisons and many others.
WebPageTest: How to use the tool?
- To get started, go to the WebPageTest homepage and enter the URL of the page you want to test.
- But you can also scroll down the list of options and choose the type of test that suits you between Core Web Vitals, Lighthouse, Visual Comparison or Traceroute.
1. Defining the test parametersWebPageTest offers two types of parameters to perform your tests, simple and advanced.
The simple configurationThe parameters of a simplified configuration on WebPageTest are very easy to set up: You simply choose a desktop or mobile configuration with a 3G, 4G or cable connection. By default, the platform chooses a 4G Mobile configuration emulated in the United States from Virginia.
- Once the connection and type of connection have been chosen, you can check the boxes:
- “Include the repeating view”
- and “ Run a Lighthouse audit ”.
Advanced ConfigurationWhen it comes to advanced configuration, WebPageTest offers a plethora of options worth exploring. This makes the platform a powerful tool suitable for developers. But even for a beginner, there are some easy-to-set options (missing in the simple setup) that can be very handy.
- To get started, click on “Advanced Setup” to drop down the section and access the available options.
- To get more options, you can switch to the other tabs and further specify your configuration criteria.
- Click on the “Launch test” button to start processing your request.
2. Get a performance overviewOnce processing is complete, WebPageTest displays a site performance overview with information about:
- All analyzed metrics
- First byte
- load time Total load time
- Number Total Bytes
- And other Real User Monitoring (RUM) metrics such as First Contentful Paint and Time to First Byte.
- Click on the “Performance Summary” field to drop down the list of tabs that we will now present one by one:
FilmstripAs the name suggests, this tab presents a filmstrip view of your site’s load time. On each image present on the filmstrip, you have the waiting time necessary for Internet users to obtain it on their screen and the percentage of loading that the image represents on the complete display of the website.
- As you scroll through the filmstrip, you have a red marker indicating your position on a waterfall chart.
Requests detailsCompared to the previous one, the “Requests Details” tab is a bit more technical. As the platform says, “this page can be used to explore metric timings and request a cascade for any run of your test.” The “Details” tab has 6 parts namely:

ContentThe “Content” tab provides information on how the resources of the analyzed site are composed by type of content.
DomainsOn this page, you have a distribution of content by domain. Depending on the site architecture, the tab can display one or more domains. And looking closely at the pie chart, we can see that a percentage of queries and content come from Google Analytics and Google Tag Manager.
ProcessingHere you have a processing breakdown that shows:
- The different processing categories
- The processing events
