[jira] [Comment Edited] (PDFBOX-5169) PDFMerger produces overly
large output PDF

No idea yet, some things that could be investigated when more time:
- removing structure tree
- run the error check from the merge test class on the structure tree
- try the same on a split PDF and compare
- read and save the 3.0.0 result with the 2.0.23 code (is 3.0 result smaller because the support of compressed object streams in 3.0 ?)

> results in an overly large file. The two input files are 1,25 MB and 16,3 MB large, while the output file is just over 400 MB large. The action also consumes about 1 GB of memory. No errors are produced during the merge that I can tell.
