> I don't like it either, but I totally get it when when Synapse+Element are still a slow inconsistent error-throwing mess if you don't disable federation
It isn't really. I can't confirm this despite being part of the biggest rooms in the network on matrix.org.
It was slow (very slow) once (when Matrix grow and Synapse wasn't scalable), but that has been in the past for a while now
I tried this, weeks ago. Joining rooms timed out on the client, and took about an half an hour to an hour to sync up to a point I'd assume it'd be reliable. Sort of. That's probably all fine once you're settled in, but "the largest rooms" aren't even close to as active as a typical Discord server. It'd be a horrible drop-in replacement for Discord right now.
largest in amount of servers that are participating (which actually makes the biggest resource impact).
What did you do for half an hour sync time (I guess initial sync when you login the first time with Element?)
