I would profile your whole app to see how your time is being spent (as in actually using the profiler).

Also what type of images are you dealing with?

As you can see I have the timing of every single operation, "white.jpg"
is a simple jpeg "all white" image 600x600 pixel.
I have removed the JPEG writer and inserted a PNG one, in this situation
the graphical output is incorrect, (I can't see the little red line).
