The PDFBox document is in two versions as I tried to optimize the size by
avoiding calls to setContentStreamFont(...) and setNonStrokingColor(...) if not
strictly necessary.
Nevertheless, as I could except, the size of compressed document changes very
little.
First page of smallest PDFBox file has 127 (!) content streams, many of
them empty (but Flate compressed so it costs about 29 bytes extra), most
of them tiny. You can see that with PDFDebugger.
The itext file has only 8 content streams.

Good morning.
I have an issue concerning the size of generated PDF files
I have generated some (almost) identical PDF files using iText and PDFBox.
When uncompressed, the sizes are comparable, while if I use
compression (in PDFBox I set to true parameter "compress" in
constructor of PDPageContentStream), the PDFBox ones are much bigger
(around 2 to 5 times bigger).
Is it a known issue? Is there a way/workaround to have smaller sizes?
Could I leave the files uncompressed and use a separate library to
compress them?
Please upload the files to a sharehoster so that I can have a look at them.
