Created attachment 15703 [details] OpenJPEG_Luratech_JPX.xlsx I ran Ghostscript on PDF files that use JPXDecode filters for images, and there are some files where OpenJPEG is significantly worse than the Luratech decoder. First, we should validate this performance difference (possibly with mupdf). After validation, we should look to see if we can identify performance bottlenecks in OpenJPEG, or determine if the memory usage can be improved.
