So, your blog is growing fast or you’re worried that your visitors will start increasing quickly but your WordPress based website or blog is slowly starting to slow down. You’re panicking and you start to get worried that your rankings will start falling down, visitors will get frustrated at your site and your site might possibly go down.

Well, we’re here to give you a simple and quick tip to reduce the resource usage of your WordPress blog while increasing the overall performance due to the decreased load that your blog will generate, all you need is 5 minutes and FTP access to your blog.

The wp-cron.php file runs with every single page load by default on WordPress blogs, which means that for every 1 request you get, you generate another one. This effectively translates to 1000 page views are actually making 2000 requests, which doesn’t make sense!

define('DISABLE_WP_CRON', true);
