------------------------------------

> pdf creation very slow
> ----------------------
>
> Key: PDFBOX-3382
> URL: https://issues.apache.org/jira/browse/PDFBOX-3382
> Project: PDFBox
> Issue Type: Improvement
> Components: FontBox, Writing
> Affects Versions: 2.0.2, 2.0.3, 2.1.0
> Reporter: kazu
> Priority: Minor
> Labels: optimization, performance
>
> compared to older 1.8.x versions, the new 2.0.x branch is awesomely slow.
> benchmarks using a multipage document with few images and many text-lines
> indiciate a performance penalty of about 1:20 compared with the old 1.8.x
> branch.
> profiling via VisualVM indicates that the new font handling causes this
> performance drawback:
> TrueTypeFont.nameToGid() [31%]
> TrueTypeFont.hasGlyph() [23%]
> PDFont.getWidth() [16%]
> PDType1Font.encode() [9%]
> is there any workaround for this? the current setup only creates about 10
> PDFs/second compared to over 200/second for the 1.8.x branch...
