add_action( 'init', 'stop_heartbeat', 1 );
function stop_heartbeat() {
global $pagenow;
if ( $pagenow != 'post.php' && $pagenow != 'post-new.php' )

By including the above code within the functions.php the heartbeat API would be disabled everywhere except the post.php and the post_new.php pages. This is the best choice wherein you dont want to re-enable and disable it after you are done finishing the task. But the resource usage will still be significant.


NOTE : For you to maximize the efficiency of the above variation of permitting Heartbeat we would endorse you to live logged in only when doing something significant. In case you aren’t using WordPress then it’d be a BEST to log off and work on different task.
