Ok, some more info. I'm on an Linux AMI instance on Amazon EC2, and on my
Windows 7 desktop. Patch is slower on both. I'm using Oracle JRE 1.8.0_111. Not
openjdk.
The code is kind of standard page rendering, from examples. This is a snippet
of parts of the code, but I think it is clear enough:
PDDocument doc = PDDocument.load(pdfFile);
PDFRenderer renderer = new PDFRenderer(doc);
BufferedImage image = renderer.renderImageWithDPI(0, 110, ImageType.RGB);
image.flush();
doc.close();

PDFRenderer renderer = new PDFRenderer(doc);
BufferedImage image = renderer.renderImageWithDPI(0, dpi, ImageType.RGB);
File file = new File(String.format("%s/%04d.jpg", pictDir.getPath(), pageNo));
output = new FileOutputStream(file);
ImageIOUtil.writeImage(image, "JPG", output, dpi, quality);
image.flush();

> I've a private pdf containing 1900 tiny inline images (CMYK, 8bit) which
> renders way too slow. Again the CMYK2RGB conversion is the culprit here, BUT
> the known issue with the KCMS/LCMS change isn't the main problem here.
> I ran some tests on linux (PDFToImage time -imageType png -resolution 150)
> 1.6.0_37: 355s
> 1.7.0_25: 289s
> 1.7.0_75: 298s
> 1.8.0_101: cancelled after 15 min
