PDFBox Colleagues, Any ideas? ---------- Forwarded message --------- From: Tim Allison <talli...@apache.org> Date: Tue, Feb 26, 2019 at 12:13 PM Subject: Re: Very slow PDF parsing. To: <u...@tika.apache.org>
Sorry...that's an OCR tool. One thing that can slow down processing dramatically is if you have tesseract installed (try typing 'tesseract' on your commandline) and if you've turned it on for PDFs. I suspect this isn't your problem, though.
