WordPress has ability to schedule posts, so our posts can be published in the future. This feature uses WordPress cron system, not a real cron, but something like virtual cron. Yes, because it use a file called `wp-cron.php` to do this task. This is useful of course. But, if you don’t need this, you can completely disable it.
All you need to do is add a line of code on your `wp-config.php` that prevent cron to run. Open wp-config.php using your favourite code editor. Find a line contain define('WP_DEBUG', false); and add define('DISABLE_WP_CRON', true); after it and save the file.
define('DISABLE_WP_CRON', true);
