Open large PDF documents


We need open a document of more than 12GB and generate others from a range of pages. However, it takes a long time to open the document (7 days).
We identify that the application uses a maximum of 39MB of 16GB RAM and 13% of my CPU i7.
How can we make it faster?
Can we configure it to take advantage of the hardware?

Thank you.


Thanks for contacting support.

Please note that larger PDF documents take more time to load because once a Document object is initialized with larger file, all of its content and structure are loaded into memory. However, we improve API performance and memory consumption in each monthly update of the API.

Would you please make sure to use latest version of the API i.e. Aspose.PDF for .NET 18.12 and in case you still face performance issue while loading the document, please share the document with us by uploading it to some public file sharer and providing us with link.
