Improve performance for long-term survival worlds (500–1000+ days)

Hello Mojang team, I really enjoy playing Minecraft for long survival sessions, but I’ve noticed a serious issue after surviving around 500–1000 in-game days. The world starts lagging heavily and becomes difficult to play. Could you please optimize the game for long-term survival worlds, so that players can continue without severe lag after many in-game days? This would make the survival experience much more enjoyable for those of us who like to keep one world for a very long time. Thank you!
