Dear Indra,

as nobody answered yet I can give you our experience but please understand that this might
be biased as I’m a committer at PDFBox and the result is based on the document content we
are merging. 

For a project (a banking customer) we needed to post process (add paper handling marks) and
merge large batches of documents (up to 5000) with the merged PDF containing up to 30000 pages.
For various reasons an Open Source library had to be chosen but we did some testing using
closed source products.

At the time we did the tests PDFBox was 5-10% slower than iText and produced larger files
(10-15% larger). Both were considerably slower than the fastest closed source product (PDFLib)
we tested which also produced smallert files. The tests were done approx. 2 years ago and
both PDFBox and iText moved on. I don’t have newer numbers for you.

We did choose iText but replaced that approx. half a year ago with PDFBox. That decision was
made mainly because of the Apache license and as PDFBox’s functionality and performance
was sufficient. We are not using the PDFBox MergerUtility but a custom one which is tailored
to the content of the documents we are merging - e.g. there is no need to merge AcroForm content
but we do merge bookmarks.

I’d recommend that you give both iText and PDFBox a try - it shouldn’t take you more than
an hour to have a simple test program for both to run against a testbed. 

With kind regards
