I gave it 4 CPUs and 8GiB RAM for my instance.  The videobridge seems
to consume ~10% CPU per connected user.

Server seems to use about 500MiB ram idle, each video stream doesn't
seem to use too much RAM, maybe 30MiB per user.

It seems that each user consumes about 1.5Mb/s of network bandwidth,
varies depending on res and quality.

I've only tried my instance with 3 or 4 users.  Aiming to try it with
a few more this week.  On the whole I've been reasonably
impressed by it, very feature rich video conf tool.

Downside is their install documentation is rather non-existent and
there are only packages for Ubuntu.
