Resources By File Type
Total File Count by Domain
We break down the data in two ways. The first is the total number of files of each type being loaded by your users over time. This is interesting because it immediately will tell you if you performance issues are caused by a spike in resource loads. Or, if one kind of resource suddenly overtakes another in total count, it’s a good bet something is going on that’s worth investigation.
Request Metrics shows you an overall graph of file counts over time, so you can see if the marketing team is getting too aggressive with the tracking pixels or ad providers.
There is also a summary that will display the total number of files by type. This is useful to see, at a glance, which kind of resources your pages are loading most. For example, if you’re having Web Vitals issues and your pages are mainly loading images, it might be a sign that you should look at optimizing your image loading strategy.
File Counts per Page Load
Resource Types by Domain
In addition to the top-level graphs, you can see file type information for each domain your page loads resources from. You can see your domains from a “total count” perspective:
Or from a “per page” perspective:
Each column is fully sortable, so you can focus on specific file types and see just who’s responsible for the data. You’ll be surprised just how chatty third party tools like Google Analytics can be!
