I have searched in the forum but I could not find current information about this topic.
Our system aims 5 million users and needs a small response time. I found an answer from 2012 which Alex claims that one Openfire server can handle 200.000 active users.

So do you think this is true? Also what is the current maximum active connection Openfire can handle for now? (Openfire 3.9.3)
