Well, there are lots of way to _increase_ the rendering time. I would
try putting in parallel a thread that does random trigonometric operations
in a tight and endless loop for example :-p
If, more seriosly, you want to _decrease_ the rendering time, you may want
to disable antialiasing (don't remember if it's enabled by default):
RenderingHints hints = new RenderingHints(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_OFF );
renderer.setJava2DHints(hints);
Also, if the dataset is small, try to preload it into memory by using:
Map rendererParams = new HashMap();
rendererParams.put("memoryPreloadingEnabled",new Boolean(true) );
If not, maybe you may want to try out another data format that performs better
than the one you're using, or, if you're using exclusively shapefiles, to use
the shapefile optimized renderer.
