Hi,
Me and my friends are playing over a 4 months on my friend's server and it is laging so much. We play on vanilla with 5 datapacks but no mods. I don't know if this is "normal" on Aternos but when i play alone on the server, it is fine without lag but when my second friend come it get's a lot worse and the server can't hand it. It loads like 1 chunk when i fly with elytra or ride a boat on ice and everything is so slow, for example breaking blocks takes so much time, i have to dig one block like 3 times to actually break it. The console nonstop says the server is overloaded. When my third friend comes, you probably know what's gonna happen 
Our world is big about 700MB so this is maybe what it causes.
Is there any way to reduce the lag on the server? BTW this starts happening on every my server after like 3 hours of playing. Pls help
Thanks
