Comment (by jeffr0):

 In response to the issues David Anderson brought up when the API was in
 initial development concerning server performance, InMotion Hosting did a
 nice writeup and experiment showcasing the performance impact of the
 Heartbeat API on their servers.

 php-usage#heartbeat-in-action

 There's also quite a few reports from HostGator customers in particular
 that routinely have their site suspended with POST /wp-admin/admin-
 ajax.php labeled as the culprit. I experienced this personally when I
 hosted a site on HostGator and upgraded to WordPress 3.6. I'm not sure how
 widespread of an issue it is today, but based on comments in this article
 http://wptavern.com/how-to-take-control-of-the-wordpress-heartbeat-
 api#comments it's still happening.

 The problem is solved by either slowing down the Heartbeat API, moving to
 a host with more lax resource restrictions, or purchasing a VPS.
