Another great performance tip is to adjust what zoom levels different layers are visible. A building layer does not have to be visible when viewing a 100x100 kilometer area. Anything else that does not make sense drawing in the map when zoomed all the way out should be set only visible in the inner zoom levels. Tweaking the different zoom levels that layers are visible can increase performance quite a bit. Also splitting a forrest layer (or other layer with many complex polygons) in two, where you have a decreased the amount of points in the polygons for the outer zoom levels and have the fully detailed polygons in the inner zoom levels can speed up the map quite a bit. Most Desktop GIS application have a feature to decrease the amount of points in polygons or lines. Imagine a shore line with points for ever meter and you have to draw this at 1:1000000, most of the points in the shore line will fall within the same pixel. Having a low detailed version for the first zoom levels will increase performance a lot.
