You may have heard that #BigBlueButton is not suitable for large meetings? This is what a #BBB meeting with 100 participants looks like on one of our BBB cluster nodes. CPUs stay below 3% the whole time. We have seen Meetings with 400+ participants running fine on our hardware. Large meetings are no problem for BBB anymore, and that has been the case for a while now.

I just found metrics for a meeting with 108 webcams enabled at the same time. I have no idea why you would want to do that, but server CPU load for that particular meeting was below 8% the whole time.
@mhellka That aligns well with our latest numbers at @infrarun. Meetings with around 500 people work just fine. If somebody wants to give this a try, possibly with even more participants, HMU!
