I'm wondering whether this is a flaw in the current implementation, that
each stream will always use a multiple of 4K instead of the actual size
(at least when the size is known in advance).
But the thing you mention, 1 stream for 1 page, will obviously have to stay.

Hi. What are your PDF memory settings? I was looking at the code and doing
some profiling last night and it looks like the temporary file optimization
keeps 4K of data per page in memory. For 200 pages, this would take 800K+ of
memory just for this.
I have been using PDF box for a while now, but have a pretty simple use case
and so haven't used many of the features. However, we had a user create a
document with 10,000s of pages recently, and the 4K / page started to really
show itself.

Hello,
I am evaluating to replace our pdf processing from itext to pdfbox.
I have some performance issues with pdfbox in comparison to itext.
Here is the link to stackoverflow where I described my problem:
