I'm experiencing a lot of server lag while playing on a Realm with only one other person and they're very close by to me. It isn't that bad when I'm mining or walking, but flying has a lot of rubber banding. It stops me in my tracks so I have to regain my speed. It makes flying insanely annoying and difficult. It also still consumes whatever rockets I used even when it sends me back. This wasn't a problem before updating to 1.18. I'm assuming it's because the same servers are trying to deal with so many more blocks without the servers upgrading at all.

Also going to the nether, me and another person on the server were killed by Piglins before we could even load in. If this was a server I was running, I'd assume it's just my fault, but this is an official Realm.
