Daniel Persson created PDFBOX-4296: -------------------------------------- Summary: Question: Performance Key: PDFBOX-4296 URL: https://issues.apache.org/jira/browse/PDFBOX-4296 Project: PDFBox Issue Type: Improvement Components: Rendering Affects Versions: 2.0.11 Reporter: Daniel Persson
Hi Team. We use a tool we built using PDFBox to extract text for about 10k pages per day. Then we have another tool to extract images using Poppler. We want to use PDFBox for both tasks but sadly we see a performance hit using PDFBox in the order of 3 times. Do you have any backlog / technical dept / ideas on how to improve performance? We have tried -Dorg.apache.pdfbox.rendering.UsePureJavaCMYKConversion=true and that made image generation much slower. We have set System.setProperty("sun.java2d.cmm", "sun.java2d.cmm.kcms.KcmsServiceProvider") in code. We use image libraries from twelvemonkeys, pdfbox and the standard jai project. I've read in the code that we do double writes for images using transparency which might be a culprit. I have been allowed to put some time into the project if we have some solid leads or a roadmap to reach better performance. Hope it's okay to track this issue here instead of a question on the mailing list.
