Does a personal Jitsi server improve performance?

Hi

I’m trying to use Jitsi to automatically start a meeting and enter it when I start up my Raspberry Pi 4B. I tested it through the browser and performance is alright.
What are the advantages of running jitsi on a personal server?

Thanks

Definitely better experience - depending on the resources you commit to it. You have more granular control and can manage ‘roles’. The fact that you don’t have to share resources with a gazillion other people means you’ll (almost) always be guaranteed a remarkable experience on your Jitsi installation. The benefits are endless, really.

Thans for your reply.
What server specs are recommended? Right now I experience a lot of lag and stutters.
