{quote}The resource cache is already passed to the colorspace and could be
extended to manage such a cache.{quote}
Wow thanks, I hadn't noticed that... despite that I had committed that one
myself in PDFBOX-4411. Rendering is now done in 10 seconds. It needs a change
in 4 classes (not the ICC class, because it's always the same ICC colorspace
object), I'm going to run some tests first.
