wp-cron vs custom cronjob on large multisite

Hi,

I wish to ask if someone knows what could be the better choice if the network become large enough, for example more than 1000 blogs.

I read many post online about using wp-cron or disabling it and using a manual cronjob instead. The question become hot if the wordpress install is a network instead of a single site. Because every site has it’s own wp-cron scheduling.

What I learned reading online is that to improve site performance, or, more in general, to reduce server load, it’s possible to disable the default wp-cron and set a custom cronjob server side, using cpanel.

But, if you wish to use a custom cronjob in a wordpress network you need to use a custom script to execute the wp-cron.php on every blog.
I found a valid post with code here:

Someone could give any suggestions or could share any experience about this?

Thank you very much in advance!
