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(); was (Author: barsk): Ok, some more info.
