> Reduce number of copies to lower memory footprint
> -------------------------------------------------
>
> Key: PDFBOX-5685
> URL: https://issues.apache.org/jira/browse/PDFBOX-5685
> Project: PDFBox
> Issue Type: Improvement
> Components: IO
> Affects Versions: 3.0.0 PDFBox
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
> Fix For: 3.0.1 PDFBox, 4.0.0
>
>
> The user bnncdv reported some regressions in 3.0.0 on the [users mailing
> list|https://lists.apache.org/thread/qs0gxwnbb57j0bpndr4zxr9y4pr16593].
> If an input stream is used as source for a pdf every time the parser creates
> a view a copy of the RandomAccessReadBuffer holding the input stream is
> created. The duplicated byte buffers are reused but if it comes to larger
> pdfs the number of duplicated objects matter.
> I was able to reproduce that behaviour.
