Loading world is taking so slow.

Hey Mojang! I have a issue for you. When I created a world, the loading screen of Generating World is taking so slow. You said that it cannot support 700MB of RAM while I have 2GB of RAM. I installed Roblox, Among Us, Minecraft and cleaners. Why did I need more RAM to load Minecraft 1.16.100? I am now downgrading to Minecraft 1.16.40. I want to know.
