What I don’t like with Matrix is the load it puts on the server. It basically copies 100% of a room content to any server having one or more users registered in the room.
Retroactively?? I’m sure that one could configure this to not be the case… no?
So if you’re on a small server, and one user decides to join a 10k+ large room, your server may collapse under the load as it tries to stay in sync with the room’s activity.
“Collapse” meaning what, exactly? Do you mean run out of storage from the volume of content, or that processing all the messages is too taxing?
XMPP, on the other hand, has proven to be highly scalable
How does it scale differently than Matrix?
I’m not even sure I want a messaging account linked to any of my Fediverse accounts…
