Depending on what machines you expect your software to run on, it
might be worth a note CoreImage is exceptionally slow on some
machines. Simple CI filters like "blur" easily take up 30 seconds in
cases GraphicConverter or Photoshop need 3 seconds only, using their
own algorithm.
Not sure wether this is bound to the processor (500 MHz G3, 640 MB
RAM) or to the graphics card (ATI RageM3, 8 MB, "Core Image not
supported").
I'd strongly suspect that the CoreImage developers optimized for G4 and
up. Very few users lack Altivec nowadays. And of course, with a
supported GPU, the rendering happens on the video card, which is hard to
beat.
IOW, on a more recent piece of hardware, CI is exceptionally fast.
