           Summary: poppler is too slow when opening PDF 1.5 files
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: general
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: ousia at wanadoo.es


I have just discovered that evince (and also xpdf) is much slower
dealing with PDF 1.5 documents than it is with the same document in PDF 1.4.

Here you have the test files (both generated with the same XeLaTeX binary):

http://www.tei-c.org/release/doc/tei-p5-doc/en/Guidelines.pdf (PDF 1.4)
http://users.ox.ac.uk/~rahtz/Guidelines.pdf (PDF 1.5, much smaller)

Evince and pdfinfo show a huge difference when opening both versions and
acroread 9.3 and mupdf-r938 show a 25-30% time increase when opening the PDF
1.5 version.

Tests bellow. Guidelines.pdf is the PDF 1.5
document and TEI_Guidelines.pdf is the PDF 1.4 document.

I hope it helps,


Pablo
