I am trying to figure out how to deactivate the internal WP cron (via wp-cron.php executed on every pageview) and use the native linux-cron.
I am looking for "better" performance by running the cron once every x minutes (maybe 5 minute interval).
BUT this simple task (on standalone WP installations) proofs to be a lot more difficult on WP MU installations. There are no resources I can find on this topic.
I know this is a rarely used feature but it must be possible and that without degrading performance on growing installations (number of sites and hits on the WP MU installation).
Any experience or ideas?
