1.16.100 is VERY lagy

You feel the lag even in a new created world. I cant be in my storage of my survival world anymore. To lagy. Bevor I could load 100 chests instently. Now it takes 3 seconds to open a craftingbanch a chest or a villager. Im not able to craft items (it tskes to long) because of lag. I have 2 devaises(Samsung): Tablet(Tab A6)  and a phone(A3 2017, Android 8). Bouth have the same issue.

Lag and long loadingtime of inventories. Chunks load very slow.

Please remake this point. Privious versions where just fine so it's about 1.16.100.
