Real-Time Performance Metrics

The Sonar Lite Extension uses RUM (Real-User Monitoring), which gathers information about your browser’s connection to the Internet and your desired website. Sonar Lite uses this data to determine how fast a web page loads in your browser and can detect errors or latency in your connection.
You can use this information to optimize your website’s performance.
