The real reason could be that Mono=4bit grey, Color=12bit color.  Thus the
framebuffer on the megapixel display is 512KB for Mono, vs. 1.5MB for Color.

Since there is no intelligence on the display hardware (unless you are using
a Dimension board :-)  ), just a lot of block-copy operations (and
double-buffering in system RAM), you will see a speed difference.

Plus the Display PostScript interpreter has less stuff to rasterize.
