 * When I use your cache plugin, admin-ajax.php loads on page load and you can see
   the message
    `action:optimisationio_page_load_time` in the Network inspector 
   in Chrome. It slows down the page load, as tested on pingdom and other webspeed
   tools. I even disabled heartbeat in your WP Disable plugin. Other cache plugins
   don’T do it. Is this a bug or why is it happening?

 * Having the same, do you use wp disable as well? Since it might be that one and
   not this plugin per say.
