SPOF Evaluation

The domains below should be tested for SPOFs
using WPT to blackhole specific domains

Select one or more domains that you would like to test.

A new window will open in WebPageTest with the
selected domains automatically populated in the SPOF feature.

Performance Evaluation

The domains below may be impacting performance.
Run tests to block specific domains
(You can copy these into WebPageTests's block feature
To test how the page will load with them blocked.)

The block feature can't be automatically populated, so these need to be copied manually.

Once you run some tests, compare the results to your initial test
