> We use PDFBox to save the first page of a PDF as an image to provide a
> preview of the document. These PDFs can be relatively complex as they may
> contain ten thousands of objects, especially map data. The results are still
> fine, but when we upgraded from 2.0.20 to 2.0.21 we had a notable performance
> decrease. Saving the first page of the attached sample document now takes
> nearly 20 sec on my developer machine, compared to 4 sec with 2.0.20.
