Last N for handling multiple participants?

Hello,

I want to achieve this scenario in my OCTO setup

There are, lets say, 50-100 or more users for a webinar and this is the use case

The first 5 users, who join the meeting should be able to see/ hear each other

The other 45-95 users, cannot switch on their mics or cameras, but can just see the first 5 participants

Correct me if I am wrong, Last N is the correct setting for this right ?

In my OCTO infrastructure, there was a very heavy RAM and CPU usage when we crossesd 50+ participants

You can livestream the meeting of the 5 active participants to the other users through a stream server. LastN doesn’t prevent the second group to unmute itself
