Some more ideas:
- I have about 30 files that are slow or were slow (but many still are),
if you like to investigate for "opportunities"
- the one I mentioned yesterday renders in better speed with PDF.js.
I've never heard that they use the GPU, usually they are faster than us
- video about PDF rendering in general by the PDF-Tools boss:
https://www.youtube.com/watch?v=TiqDqd-1pwU&t (very scary!)
- video about PDFBox https://www.youtube.com/watch?v=Sf8BfGaRUkk and
https://www.youtube.com/watch?v=agzqehWt-ko
- you're not the first person who would write a thesis related to
PDFBox, this guy wrote about text extraction:

Dear Sir or Madam,
my name is Stefan and I'm working at CAS Software AG, a company in Karlsruhe.
Currently, I'm looking for a topic for my master thesis.
As we are using your library PDFBox for document to image conversion, I had an
idea for a topic. But first, I would like to ask you,
if there has been some investigation, or developement by your team before,
regarding this topic.
The basic idea is, to increase performance of the document conversion by using
hardware acceleration (GPU).
If I'm right, there is no computation done by the GPU at the moment. Which
means, that everything during document conversion
gets processed by the CPU. My assumption is, that the GPU could be used for
transforming elements, such as text/glyphs, images, etc. to their final
size and position. I assume, that this increases the performance.
The question is, if there has been any investigation with respect to hardware
acceleration.
I very much look forward to hearing from you.
Best regards,
Stefan Sauerer
