Performance Report for https://www.brighamandwomensfaulkner.org/about-bwfh/news/new-building/default
Category Audit = performance
The performance audit in Lighthouse consists of several stages:
1. Data collection: Lighthouse launches the browser and loads the web page to collect data about its performance.
2. Metrics analysis: Lighthouse evaluates performance metrics such as page load time, content rendering speed, cache usage, and more. It also provides information on how each metric impacts the user experience.
3. Report: Lighthouse generates a report that contains the results of the performance audit. The report includes a list of recommendations for improving page performance and an assessment of each performance metric.
After conducting the performance audit in Lighthouse, you can use the data and recommendations to optimize your web page's performance and improve the user experience.
