Whenever a user access your blog, wp-cron.php is called automatically on each request. On a low traffic website, this is not a problem but if you have high traffic websites, this can result into high resource usage and it can also affect the website loading.

It is possible to disable this virtual cron file (wp-cron.php). We can do it by adding necessary code in wp-config.php.

[1] Open your wp-config.php file.

[2] Add the following line in your wp-config.php file after your database details (after define(‘DB_COLLATE’, ”) line):

define('DISABLE_WP_CRON', 'true');
