What is behavior of a Network Monitor when it is under heavy load?

Hi,

I am looking for an explanations on the system reaction, including Monitor, Enforce and any other components, when a Network Monitor comes under heavy load? For example, the span sport send a large number or network packets, the CPU utilization on monitor goes up, etc?

Are we start seeing longer wait times, longer incidents queuing, wait times, or there is potential packets drop? Is there any related KB articles on the subject?

We are running ver. 10.5, preparing to migrate to 12.0

Thanks!

Alex
