When you measure your site, SpeedFactor uses two separate methods:
1. Google Lighthouse, an automated tool for improving the quality of web pages, will audit your site for metrics like first paint and time to interactive to determine lag.
2. A custom-tailored Simulated User Monitoring audit, testing for raw data related to pageload timing, such as connection, redirection and Time to First Byte.
SpeedFactor will then save all this data and show its progress in a daily chart. This is useful for event monitoring and for experimenting with various site features, content management systems, cache systems, database queries and resource requests.
