Itai Shaked commented on PDFBOX-4392:
-------------------------------------
Thanks for the problematic examples Tilman!
Looks like I was reading the length wrong, and upon fixing this the results are
almost exactly back to the original version. I'll try looking into it again
later, as it seems at least some improvement should be possible, but for now -
sorry for the false hope!

> Hi all
> The issue is pretty straightforward. I receive a lot of pdfs every day and
> render them. In most of the cases everything is OK, but PDFs which produces
> WARN org.apache.pdfbox.pdmodel.graphics.color.PDICCBased - ICC profile is
> Perceptual, ignoring, treating as Display class
> working super long, and are super memory consumable.
> It takes from 5 to 15 min on m5.large amazon instance. But attached PDF
> completely killed the instance. The java process is just killed by linux
> during processing with no exception in logs.
> So could you please provide explanations what is going on with files with
> WARN message above, and how can I improve the rendering.
>
> Here is my VM options
> -Dorg.apache.pdfbox.rendering.UsePureJavaCMYKConversion=true -Xmx3G -Xms2G
> -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider"
> Also don't hesitate to ask me about more PDF, I have tones of them :D
>
> And also a question, does GPU have influence on rendering?
