>    Affects Versions: 2.0.2
>            Reporter: kazu
>            Priority: Minor

>             Fix For: 1.8.12

> 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...
