Hi there - We received the following note from our hosting company asking if anything could be done about missing cache for the ajax-admin calls. Here's the note:
_We're seeing a lot of expensive/un-cached admin-ajax requests being made on every page of the site. These requests are always missing cache, which means that they have to be processed by PHP and are therefore causing high CPU load on the server when a large number of such requests is made in a short amount of time.
The admin-ajax requests belong to the buttonizer-multifunctional-button-premium plugin and looks like this:
GET https://www.example.com/wp-admin/admin-ajax.php?action=buttonizer&qpu=b2bad81de1154ee0a2a112a5f35776b0&preview=0&data[page]=3000&data[blog]=1&data[is_404]=false&data[is_front_page]=false&data[title]=Retail Industry&data[url]=https://www.example.com/retail-industry/
Responses to such requests are also setting the following cache headers which mean that requests are never cached:
cache-control: no-cache, must-revalidate, max-age=0_
Is there any chance we can add a cache to reduce the high CPU load on the server?
