Spire PDF merge large file processing taking long time

[sandip.jain]

Hello,
We have license of Spire PDF and we are trying to merge following PDF file into one.
PDF 1 size --> 307 MB (10614 Pages)
PDF 2 size --> 237 MB (9434 pages)
PDF 3 size --> 128 MB (6285 pages)

it is taking taking to much time to merge all this files. We have waited for 15 min and process not completed, so we have to kill that process.
can you please let know how big file we can merge? How big files you have tested so far?

Please find below code for merging
inputDocument = new Spire.Pdf.PdfDocument(file);
outputDocument.AppendPage(inputDocument);

Please let us know if there is any optimal way to merge these files.
We have also downloaded newer version of Spire PDF DLL ( V 3.5.0.5040)

Thanks in advance
Sandip

Hi,

Our dev team made an adjustment for the code of the merging function yesterday, today our test team did a test, but the results were not good, just raised a few minutes. Our dev team will continue to investigate this issue to find better solution to effectively shorten the running time.
Thanks for your cooperation and understanding.

Hello,
We are doing performance monitoring using JetBrains tool and we have found that certain functionality of Spire is taking long time. Please find attach screen reference for the same.
Please provide update ASAP or we need to buy other license for the same.

Hi,

Please download and test new package.
http://www.e-iceblue.com/downloads/Temp ... .5.117.zip
The new package may not be able to reduce to 4 minutes for your large pdf files. If you just want to combine the multiple documents, we suggest you to choose the way to add attachments, it is very quick.
Sample code:

Code: Select all

PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("..\\..\\test1.pdf");
            string attachmentFilename = "..\\..\\test2.pdf";
            var attachment = new PdfAttachment(attachmentFilename);
            attachment.Data = File.ReadAllBytes(attachmentFilename);
            attachment.Description = "Test2.pdf";
            attachment.MimeType = "application/pdf";
            doc.Attachments.Add(attachment);
            doc.SaveToFile("attachment.pdf");
