Even if I am in a single player world, I lag so bad it is unreal. When it comes to opening chests or opening my inventory, a anoying load bar pops up and stays for about 10 seconds, which isn't alot, but I'm a survival hard difficulty player, and I am really scared to be frozen. Also, the chunks take ages to load in, and even if I'm not far from the area, they unload and have to realod again

Steps to Reproduce:

1. [Step 1]
2. [Step 2]
3. [Step 3]

Observed Results:
lag and unloaded chunks

Expected Results:
Shouldn't be as much loading, and chunks should load and unload when they are supposed to.

Screenshots/Videos attach: Again, I play Kindle Fire, and videos and images aren't exactly easy to take.
