Fix Performance On Bedrock

I'm pleased that Mojang fixed some of the issues like the memory leaks and worlds getting deleted, however many problems still stand.

Performance is the big one here and the game was quite smooth until the copper age update which considerably lowered the fps and made some parts of the game unplayable, especially loading chunks and using interactive blocks like crafting tables and chests. 

Playing worlds with only one add-on greatly affects frame-rate and loading a marketplace map usually crashes the game almost instantly.

It also takes ages to load the marketplace and character creator, once it does load it often says I'm offline, even though I am connected to the internet.

Please fix the performance on Bedrock Edition so players can properly play it again!
