Real User Monitoring
Real User Monitoring helps you determine if users are being served quickly and without errors and, if not, which part of a business process is failing.
Page Load Time
You can view breakdown of how the load time of each page in your website looks like. Know if the DOM Processing, Page Rendering or Network Latency affects your load times.
From the navigation start till the response is received from the backend server is the complete network time. This would give you an overview of how much time your web app needs for communication from the browser to your server. This is what we categorically call as "backend call".
DOM processing is the time it takes to parse the HTML into a DOM and retrieve or execute synchronous scripts. If you have any script tags in the body of your document, their execution is part of DOM processing. If the browser starts to download images in this phase, page load timing will capture the image load time. When you see a delay here, then you would know that your third party resources could affect your overall page load time.
You can also view performance breakdown for the different browsers that your users are using by DOM Processing or Page Rendering that makes up the front-end performance
You can compare performance across different countries by Network Latency, Front-end Time or Throughput and see which holds up your users the most geographically.
