In MCBE on Windows,it takes a very very long time to enter the Nether(Almost 25s),and on Android it is better but still very long(Almost 10s).

But in MCJE,it only takes almost 4s to complete that,so this is obviously caused by a bug or program optimization issue.

Because of that,I hope Mojang can fix it and give MCBE a nice optimization.

Thanks a lot.
