Performance problem on loading and saving PDF document

In my scenario I simply load the PDF document, change a single data field and save it.

This process takes 45 seconds on my testing device (Panasonic JT-B1), the document is pretty simple ~135KB size.

Is there any way to speed up this process?

Here is my code:

// Open a document

com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(new FileInputStream(inFile));

// Get a field

com.aspose.pdf.TextBoxField textBoxField = (com.aspose.pdf.TextBoxField)pdfDocument.getForm().get(“mm2_Tenn-1”);

// Modify the field value

textBoxField.setValue(“Updated Value”);

// Set field as read only


// Save the updated document

pdfDocument.save(new FileOutputStream(new File(issuePdfFolder, fileName)));

Hi Bartek,

Thanks for your inquiry. Normally processing depends upon the fine contents/size and system resources. Please share your sample PDF document. We will test the scenario at our end and will guide you accordingly.

We are sorry for the inconvenience caused.
