Daniel Persson commented on PDFBOX-3764: ---------------------------------------- Hi Tilman. Thank you for the support. Sadly I've not read the getting started guide at https://pdfbox.apache.org/2.0/getting-started.html Been using PDFBox for reading text for years now so I've must missed this update. Now we're down to 19 seconds rendering instead of 10 minutes. :) And after I added the org.apache.pdfbox.rendering.UsePureJavaCMYKConversion the thing taking the most time is the InputStream.read function which seems resonable. Thank you for the quick response.

So a 100 times performance hit if we where to change. > I've done some rudimentary profiling on the code and found that most of the > time is spent in ColorConvertOp.filter.
