As you all know, Wordpress is the most used Content Management System on the internet and you are lucky enough that a free host like 000webhost offers one click installation of it on your domains.
It is no secret that every free hosts have some limits so I am going to propose a plugin which every Wordpress users on 000webhost should always install on their websites.
Heartbeat Control
The plugin is a very essential plugin that can reduce on the load your site puts on the server where by your website ends up going down.
Here’s why you need it.
WordPress 3.6 introduced the WordPress Heartbeat API - it allows your browser to communicate with the server when you’re logged into the WordPress admin panel. This functionality allows WordPress to handle things like showing other authors that a post is being edited by another user, plugins can use these script executions and show you notifications in real time, etc.
Even though this is a great functionality it may cause issues in certain cases. On different pages, Heartbeat makes checks on different period - on post edit, it makes it every 15 seconds, on your Dashboard - every minute, etc. Each “tick” generates a POST request which adds to the number of your executions and CPU time used.
This functionality uses the wp-admin/admin-ajax.php file to make AJAX calls.
So please do consider installing the plugin on your website.
