Where do I control a variables frequency of replication?

Hi.
I don’t know much about networking. But as I understand you, setting up the update frequencey helped a bit?
So your setting up how often it’s checking per second, but what if the server’s unable to check because - don’t know bandwidth?
So if you would set up the Net Priority it would be more likely that it’s beeing updated in time, right?
And I think you could mybe use Force Net Update Node in particular situations.
