Merge Performance benchmark

[veercv]

Hi All, I am looking for performance expectations when merging PDF files. is it more expensive to merge larger PDF files with more pages than just combine PDF 1 + PDF 2 together. can we run merging with multiple PDF files in one single action? pdf 1+ Pdf 2 + pdf 3.

Looking for best performance and what to expect for timing when we print 3K PDF files that need to merge with 15 PDF files for each 1 PDF.

Hello,

Thanks for your post. Yes, when merging PDF files, the more files or contents the more time costed. And Spire.Pdf supports to merge several files with a single action. Please refer to the below documentation for merging.
