Generic Conferencing just held a stress test for BigBlueButton 0.71. In his forum post, Jeremy Thomerson wrote "The more the merrier." At one point we peaked at 193 simultaneous users. There were 45 users in the voice conference, with one user speaking (the rest were muted). Shortly after 193rd user joined, we tried to upload a new presentation and the server stopped responding.
Earlier, we tried opening as many web cams as possible. We achieve 20 simultaneous web cams in a session.

We're very happy to see BigBlueButton 0.71 support this many users on the server at once.
Keep in mind, we don't recommend to anyone to run BigBlueButton with 193 users in a single room, but to know it's possible was pretty cool.

Hi Fred,
This is great news. I've had a report from Belgium with 63 simultaneous users listening to the audio.
What were the specs (in short) of the server (RAM, processor, bandwidth)?
Yes, the server specs are interesting for me too.
You can see the results of the stress test here:

We are going to test it with erlyvideo, which is tested to handle much more connections.
You'll find us very interested to know of any way to break BigBlueButton so can improve it.
