Description SATYA SRINIVAS K 2025-05-23 08:19:58 UTC
Description:
I wanted to have a Feature Request for LibreOffice to implement a multi-threaded method for its "Export as PDF" processing (I don't know the feasibilty and technical details inside Libre office but it's nice if that possible and improve the latency).

This would help users to view the contents of large MS Office files (containing large amounts of content) in the viewer and also "Export to PDF" in a timely manner

There are files with huge content is taking more than 40 minutes to process and export to pdf.

Actual Results:
"Export to PDF" is slower for bigger documents.

Expected Results:
"Export to PDF" should be faster with large documents , should be improved when compared to the current version.


Reproducible: Always

"There are files with huge content is taking more than 40 minutes to process and export to pdf"

Sounds like some kind of performance bug which can be addressed aside from a 
multi-threaded solution. PDF export shouldn't be much slower compared to opening and/or saving those large MS Office files, in my experience

However that would be a different bug and would require an example file (or more) exhibiting the issue. In case of sensitive data:
