I also made some tests with big PDFs with large jbig2 and jpg files, but did
not notice a difference, so I'll leave these filters unchanged for now.

The loading of the image itself is slow:
{code}
ImageReader reader =
ImageIO.getImageReadersByFormatName("JPEG2000").next();
FileInputStream input = new FileInputStream("PDFBOX-4121.jp2");
ImageInputStream iis = ImageIO.createImageInputStream(input);
reader.setInput(iis, true, true);
reader.read(0);
{code}
this takes a long time when read from a stream. Not when read from a file. And
not with this small modification:
{code}
ImageReader reader =
ImageIO.getImageReadersByFormatName("JPEG2000").next();
FileInputStream input = new FileInputStream("PDFBOX-4121.jp2");
ImageInputStream iis = new MemoryCacheImageInputStream(input);
reader.setInput(iis, true, true);
reader.read(0);
{code}
It turns out that java was providing a {{FileCacheImageInputStream}}.

There is no guarantee that the CMYK option makes everything faster. It works
best when there are many small CMYK Images. (Btw I tried setting a cache, it
didn't have the improvement witnessed for other issues).
Re the JPEG2000 warning, I didn't get that. We once had a guy who worked on
some IBM system and he lost his image plugin libraries in the middle of work.
