When your WordPress dashboard is opened in multiple tabs, its CPU load increases suddenly on your cPanel, hence preventing your website from performing well. Sadly, users can’t visit it.
So anytime you notice poor performance of your website such as reporting that you should check your internet connection or different errors, note that it is your website ajax.php one of the things to look into. When the requests on the server of your WordPress website editor is opened, you’ll see ajax requests appear every 15 seconds.
The script (admin-ajax.php) extends the user’s WordPress session for the easier use of the administrative panel. If the administrator or the editor works with the site often, it eliminates the need to enter the login / password each time.
When editing an entry, WordPress executes the AJAX request every 15 seconds. For example, to achieve 1 query per second on the server, you need 15 open editors. You may see our expert step-by-step guide on how to optimize WordPress website database via cPanel.
In many cases, admin-ajax.php is responsible for increased Physical memory and CPU consumption due to the frequent (every 15 seconds) database calls along with other requests. Since admin-ajax.php is dynamic (it can not be cached), it directs all requests right to the server which is creating a significant load.
