Slowness in opening of PDF file created in Autocad

Hi Team,

Issue :
We have a PDF file created using Autocad which is consist of some architect designs.
We are trying to open the same using Aspose - PDF (Java).
We are facing issue of slowness while opening the file in Aspose.

File size : 400Kbs
Time taken to open : 3 mins

Slowness is observed while we are converting document(pdf) to image(png).
Aspose API we are using to perform this action is : process() of PngDevice class.

You can find sample code we are using to test this scenario in file attached.

Note :

We are attaching sample screenshot of PDF file content.TestPDF.png (172.8 KB)

The document is confidential hence cannot be shared for evaluation.

Kindly help me to find why Aspose PDF API is taking more time to convert PDF to PNG .
