fair enough, that’s true. it was one of the reasons I turned off federation, even on a beefy server synapse still lagged and timed out when I would join medium sized rooms.

damn, was not expecting to see so much hate towards matrix.
it sure was annoying to set up, but once I got it up the way I wanted, it kind of just worked from that moment on. I’ve had it for some 5 months now and it works as intended with no issues, aside from some small glitches here and there which get fixed very fast (on the mobile app).
my use case was getting off Discord with a bunch of friends, so we needed a reliable way to have multiple chats, channels/rooms and good voice chat with screen sharing. element call does those well. my federation is of course also closed. for me e2ee is just a bonus
I think that if that’s your use case, it’s good for that. synapse does seem a bit inefficient but I guess you can’t do much about it
