That's a lot of drawing, so 2 seconds doesn't strike me as extremely long.
Sending the same drawing commands to an offscreen GWorld would not speed
things up, I think.

However, here's another alternative--but it won't work if you need to be able
to draw your map at different scales, or if your map data changes dynamically,
or if you need to draw it over an arbitraray background:

Write a separate program that does just this:
1. Draws the map to an offscreen GWorld;
2. Turns on picture recording;
3. Does a COPYBITS of the whole drawn map;
4. Turns off picture recording;
5. Saves the recorded picture.

Then, in your regular program, you display that recorded picture.  Because of
the way it was created, that picture is now a bitmap picture rather than a
"vector" picture.  It will draw a lot faster.  depending on the rectangle
dimensions and the color depth, it could conceivably even use less disk space
than the 264k you're currently using.
