“Page cache is detected but the server response time is still slow”

    Where can I start debugging this “critical” site health issue?

    “Page cache is detected but the server response time is still slow”

    Page cache enhances the speed and performance of your site by saving and serving static pages instead of calling for a page every time a user visits.

Page cache is detected by looking for an active page cache plugin as well as making three requests to the homepage and looking for one or more of the following HTTP client caching response headers:
cache-control, expires, age, last-modified, etag, x-cache-enabled, x-cache-disabled, x-srcache-store-status, x-srcache-fetch-status.

    Median server response time was 1,096 milliseconds. It should be less than the recommended 600 milliseconds threshold.
    There were 3 client caching response headers detected: cache-control, expires, last-modified.

    All plugins and themes are updated and run seemingly fine, however in the WordPress Site Health tool, I have this critical issue which I’ve been able to attribute to the JetPack plugin by de-activating and activating plugins one by one. Normally, I would just go without whatever plugin is causing the conflict, but this one I want to keep.

    I’ve tested turning off the image accelerators, boost, and other settings thinking there was a conflict there, but neither of those settings have affected this. The critical error is still there.

    Is there a way to dig into log files or somehow dig deeper into what is causing this error?

    Hi @tillieb20 –

    Thanks for attempting to dig into this by enabling and disabling plugins — that’s a great first step.

    To be clear, you don’t receive this message in Site Health when you don’t have any plugins enabled, but you do once you enable Jetpack? Or are there other plugins in the mix?

    You can use this tool to find more about your site speed and what may be causing the issue:

    However, in the case of a slow server response time, that is usually related to the web server itself rather than a plugin. I would recommend reaching out to your hosting provider to ask if they can look into what is causing the slow response time. It may be that your server is overloaded and/or that you are exceeding the limits of your current plan.
