Feature Highlight: Comparative Charting
The above video goes through Comparative Charting in New Relic.
New Relic Browser is tracking the performance of your sites from real end users. Synthetics does similar, where it tracks the performance of your sites, but with synthetic (fake) users.
With Synthetics Monitors running in top tier networks on AWS locations around the world, Synthetics gives you a global performance benchmark for your sites.
Comparative Charting can show you how did your real users UX differ from the synthetics checks hitting the same pages.
