With WPT you can keep track of your websites' performance.
You're allowed to have a list containing the websites you want to check.
With this list you can either enter each website to check the details about its test or test them all to see their overall performance score.
The items tested are:
- Total load time
- Bytes in
- First byte received
- Rendering start
- Total requests
- CDN usage
As soon as these items are fetched, a specific formula is applied to determine the final performance score.
