By default the wp-cron.php is run every single time a page is loaded, this includes admin pages. This can lead if you have a busy blog to a lot of cron runs, which simply aren’t needed.
What does the wp-cron do? You might ask, and even if you don’t I will tell you anyway. The wp-cron will do things like scheduled posts and can also include things that plugins want running.
So how we go about this is simple, we will disable the wp-cron from running on every page load, and then add a proper cron job.
First lets disable it:
Simply open wp-config.php and add the follow line.
Note: You need to make sure you use an apostrophe instead of single quotes in the code here, otherwise it will not work!
Second, lets add the cron:
It is probably a good idea to run the cron job every couple of hours, for this we will add something like this.

For the command you simply need to call the wp-cron either using wget OR php -q
php -q /home/cPanel_User/public_html/wp-cron.php
Personally I’d prefer the php -q option as some hosts can have trouble resolving domains on the same server.
