I know that you have probably thousands of these kind of reports but this one ima list all the lag problems I've experienced

1- placing blocks sometimes don't render 

2- the game will freeze for 20-30 seconds 

3-  Worlds/Realms/Servers take forever to load 

4- after playing for like 50min-1hour the game will lag bad i cant turn my screen with out it glitching

5- i will start to take damage for like 5 sec even on full hunger 

please fix =/
