Jitsi Meet Technical Requirements

I read here: Requirements | Jitsi Meet

For a friends/small organization server, 1 Gbits/s will often be enough but for a serious server 10 Gbits/s is advisable. Several (or many…) bridges having each a 10 Gbits/s link are used by big deployments.

As suggested in the same page, I tested the server with iperf3 :

As far as I understand 0.5 G/sec is not enough for Jitsi Meet even if for a friends/small organization server

What do you think about these tests results?

These numbers will be enough for up to 200 participants sending HD and up to 200 receiving HD streams.

Glad to hear that.

But it means that I didn’t understand this phrase:

1 Gbits/s will often be enough but for a serious server 10 Gbits/s is advisable. Several (or many...) bridges having each a 10 Gbits/s link are used by big deployments

You are asking about one machine and those are the numbers. Suppose you have several jvbs deployed on a similar machine and one signaling node. You will have 200*number_of_jvbs as the total number of participants.
This means that the bandwidth and the quality of the bandwidth is the most essential part of the requirements.
