And when discussing the two types of data, we’re actually talking about what is called real-user monitoring , or RUM for short. For example, the data is pretty slow to update, refreshing every 28 days, meaning it is not the same as real-time monitoring. But it comes with caveats. Does Lighthouse Use RUM Data, Too?
