Max rooms and users per room

Hi everyone,

I have installed some jitsi servers in good quality Cloud Servers 8 CPU, 16Gb Ram… Just I want to know how many rooms can I host and how many participants per room… or just limit of participants per server…

If I install some JVB nodes … Can I create rooms with more participants?.. for example… Can I Create a room with 300 participants?.. how many JVB I will need?

Thanks in advance and sorry for my poor english.
