PSI and domain key

    Hello,

    I have noticed an issue with the plugin I use on several websites. When I register a domain key in the general settings, I see a drop of around 15 points in my PageSpeed Insights score on all the websites. However, when I remove the domain key, the score improves by 15 points.

    I would prefer to have the domain key activated for automatic image optimization, but this drop in speed results is concerning. Can you please explain the cause of this PageSpeed Insights drop? Can this issue be addressed in a future version or is it a fundamental aspect of the plugin that cannot be improved?

    Best regards.

    Do you have the list and its difference when you have and drop the domain key ?

    The difference is in the “Total Blocking Time”. In two tests conducted without the key, the total blocking time was 20ms and 50ms. However, when the key was present, the blocking time increased to 640ms and 550ms.

    In the “Diagnostics” details, everything is similar except for the “Minimize main-thread work” category. Without the key, the results were 1.6s and 2.1s. But with the key, the results became 2.8s and 2.5s. Within the “Minimize main-thread work” section, all of the components (Style & Layout, Other, Script Evaluation, Rendering, Parse HTML & CSS) showed slower results with the presence of the key.

    Do you require any additional information?
