Description Vikas 2022-04-14 07:33:43 UTC
I have one .docx file with a file size >10MB (with content). When I am trying to convert it to PDF using the below command takes so much time.

If I upload a file that contains images and the size is >10 MB, works fine.

soffice.com --headless --convert-to pdf D:\InputFiles\word2pdf\TestSpecification_upd.docx --outdir D:\InputFiles\word2pdf

Steps to Reproduce:
1.Run given command with the attached file to reproduce the issue.
2.Then try the same command with another file that has images as content works fine.

Actual Results:
The file is taking a longer time than expected.

Expected Results:
It should not take more than sec to translate such big files.

Reproducible: Always

User Profile Reset: No

Opening TestSpecification_upd.docx is very slow (or fails, didn't wait long enough) with

Word 2003 does open it eventually and Word Online doesn't like the file either.

Actually, it does open with v7.2.5.2 but takes so much time to open and for conversion also had to wait for more than 20 mins.

I am attaching one more file which took more time to translate.

As another data point of comparison, Apple Pages on a MacBook M1 spent over 1 hour 45 minutes chewing on it (at 100% of a CPU core) and still hadn't finished opening it when I decided to just kill it. 

So, whatever is in this file, it causes problems for everything.
Comment 7 Michael Warner 2022-04-23 15:39:58 UTC
Based on Telesto's confirmation in Comment 3, I am setting status to NEW.

Yes. If you do it yourself, find or pay someone do it. 
If not, do not spam. There are bugs open for 10 years.
Comment 10 Timur 2022-04-26 14:20:07 UTC
When report starts with "I" it usually is not proper. 
7188 pages.
In this case, probably a duplicate.
