As a result, when resources can be served from the browser’s cache, the CDN bandwidth stays the same.
For example, if one user visits the same page five times, NitroPack counts that as five pageviews. However, on the 2nd, 3rd, 4th and 5th visit, the user can be served content (like static resources) from the browser’s cache. In that case, the pageview count increases, but the CDN usage stays the same after the first visit.
Larger pages with more resources (like images) generate more CDN usage than leaner pages.
If you want to know how much certain resources contribute to a page’s size, use Pingdom’s speed test tool. It has an entire section on this topic:
Also, if you’re already using NitroPack, you can test the unoptimized version of any page by adding ?nonitro to its URL. That way, you can compare the file size with and without our service.
To keep an eye on your CDN usage, check your NitroPack Dashboard regularly.
Also, the Service Usage Log has information about your daily CDN usage and pageview count.
