Realm is buggy

Hi. I have a realm with 3 car mods. 2200+ members. And my realm has been laggy for months. Mobs move slow. Slow chunk loading. My members couldnt eat because of the lag. I keep trying to fix it but all failed. I hope mojang fix this. Realm data: about 4gb. If you need realm name. Its: Realm Of USA.

 

 

Much appreciated
