Notorious Realms Lag

I just got a realm something like 5 days ago, but my Realm is already extremely laggy. My realm has 7 total people of which only 4 people are super active. Our bases are right next to spawn with no structures more than 400 blocks from it. We don't have any redstone or passive mobs or anything that could cause lag yet block placement/breaking is painful as either the block never breaks or the block never places until 5-7 seconds later. Rubberbanding is super common. All of these issues persist for all of us even though we all have above 40 mbps wifi. Clearly it's not on our end so is there some sort of server overload on the mojang end or a fix?
