I've had the same experience with som documents. This happened when the 
document was a pdf made from LaTeX with 3D postscript figures coming 
from matlab. I suppose it was because the figure shading was drawn using 
very tiny triangles, and they were so many. The pages containing such 
figures also took long time to render on screen also.

If it's the same situation, I'd suggest you change ps figures with jpg 
figures, that are much lighter.
