Chunks Loads Slowly

1.16.100 to 101 is Good update but full of bugs...
one of them is the chunks is slowly loading.
Im using A6+ and play minecraft to check on what's new
when im playing everything is fine until i notice the chunks isn't loaded fast...
it's really slow compare 1.16.40

Currently im playing 1.16.40 and i hope on the next update this bug fixed
including Mob freezing and other bug issues
