Realms Lag

Hey guys, a big hug from Mexico, so, I’ll get straight to the point, I’ve been on a realms server with some friends, and the server just lags a lot to the point that the game is unplayable, we’ve tried to delete unnecessary entities and other things, but it just gets worse, I looked up on YouTube and it seems that this has happened to multiple people, I don’t know what to do and I don’t want to cancel the subscripcion to realms, how can I solve this?

Thanks in advance guys!
