I have searched for an answer but I couldn’t find anything that answers my specific question.
I cannot see a tool for testing in the diagnostic centre?
When I pause CF (not dev mode) my site speeds up, as you can see from the results below, in the ‘Web Vitals’ (GT Metrix), with CF enabled the ‘Largest Contentful Paint’ is just over double and ‘Total Blocking Time’ is around triple.
I have tested twice with and without CF and each time I get a big difference in loading times, with the fastest being without CF.
Does anyone know how to test to see where the blockage is coming from and how to speed up the site?
