How to calculate server needs for the jitsi server?

I sthere a way to calculate server ram and cpu power according to total user in the same time?

For example with a server (8gb ram, 4 CPU) how many people can use the system in the same time?

How many meeting rooms with 30 pax each room?

If there is a special calculation table please let me no know.

A server that has 1gb port cansupport how many person in the same time?

regards

I am not aware of any calculation tools. However, here is a thread that may help:

I have seen some calculation but i couldnt understand.

For example for a group of 50 pax need ho much bandwith?

Still there is no reply.

Must be a chart by saying in 720px resolution 50 pax needs this bandwidth

480p resolution needs this etc.
