Description:
I have a word file which is more 300 pages.I build libreOffice for Android, I opened this file with libreOffice on Android, and it took 35 seconds from opening to documentLoaded.
Then I tried to open it from libreOffice on Linux, which also took about 20 seconds.
I compare it to other Android Office apps which take 1~2s to open and then dynamically render the next page, and you'll see the page number increase and load dynamically and The first View will be render. 
So I want to ask can LibreOffice optimize the opening speed of such files?

Steps to Reproduce:
1.Use Android LibreOffice Viewer
2.Open many page(more 100 pages) file(doc,docx,ppt,pptx) 

Actual Results:
from opening to documentLoaded took about 35 seconds.So Slow

Expected Results:
The loaded content is displayed first, and subsequent content is dynamically loaded.



Reproducible: Always


User Profile Reset: Yes

Additional Info:
This file I'll upload to Google Drive.
