Message: <blockquote data-quote="Weasel" data-source="post: 467155" data-attributes="member: 9520">Assuming WordPress is using PDO (but it also works similar to mysqli_*), when an instance of the PDO object is created in the script, a connection is made. Until the object is destroyed, or when the script finishes running, the connection is closed. So basically every time a user visits your non-static pages, it creates a connection and closes is once the server is done executing (/your page finishes loading). So most of the connections are short-lived.If you really have that many connections all at once, it could also be someone is DDoSing your site (layer 7), bots are indexing your site or something like that. It would be weird for a cronjob to spawn so many connections, as the script probably just would use one connection for the processing.</blockquote>
