Save to stream is very slow

[sterlingfordev]

If a document has 12,000 pages, the SaveAsStream function takes over 6 minutes.
Is there a way to shorten this time?

Loading the file stream and converting it to SaveToStream takes longer than 6 minutes. There is no logic behind it.

1 . Sample Code :

var pdfFilePath = @"D:\Users\5_50_MB_12040_Pages.pdf";

Stream stream = File.OpenRead(pdfFilePath);

using (PdfDocument doc = new PdfDocument())
{
doc.LoadFromStream(fileStream);

doc.SaveToStream(outputStream, FileFormat.PDF);

}

3. netstandard2.0

4. Windows 2019, 64 – bit.

Hi,

Thank you for your inquiry.
I used our latest Spire.Office for .NETStandard dll to test the document, it did take a long time. I noticed that the repeated PDF pages contain a lot of images, which should be the main reason for affecting the performance. Anyway I have recorded this issue with the number "SPIREPDF-6360". Our development team will do more investigations to check if there is any approach can optimize it. If there is any update, we will notify you as soon as possible. We deeply apologize for the inconvenience caused.
