Document Render using Asian Fonts is Unacceptable Slow

Aspose.PDF Product Family
1

Hello Aspose,

since we switch over from Aspose.pdf 10.4 to 24.10 we suffer from extremely slow rendering of PDFs if Asian fonts are in use. The increasement factor is sometimes >100, so many test reports fail because of testcase timeouts.
In fact our Chinese customers claim about why Aspose reports take so long to be finished.
For us this is major issue and I’m urgently searching for a workaround.

To support GB18030-2022 I created a test report to compare several Chinese glyphs.
See the attached report:
syngo.Common.Web.FontCharacterMappingReport.pdf (8.2 MB)
The rendering time is ~<4mins.

Below an example I’m using.

Regards

Could you please provide more details about the specific code or method you are using for rendering the PDFs with Asian fonts? Additionally, any specific settings or configurations applied would be helpful.
