So you had to sync all of the messages on the server first before sending a message?

That definitely used to be the case with Matrix. Sync has been improving gradually over the last year to alleviate that issue, though, assuming your server regularly gets updated and you keep your clients up to date.

Sync still takes a second in large rooms, but you no longer need to download a thousand messages just to see the three latest ones.

When was that the case? I can't remember tbh, and it would have been insane for rooms like Matrix HQ.

Maybe before 2020?

Yeah syncing Matrix HQ used to crash most home servers, probably one of the things that got it on the radar to be fixed ASAP.

Joining a room from server perspective vs syncing the client to the rooms he has already joined

At least a year ago, maybe longer. Syncing with the larger rooms in the Matrix homeserver definitely took its toll on self-hosted servers. Took minutes (at least) and couldn't be canceled.
