[OpenMap Users] any tips : Performance

Sorry if this a bit of a stupid question....
 
Can anyone give me any pointers in how to speed up the code below.
The 2 main bottle necks are proj.forward(lat[i],lon[i],pt); and return new
Area(new Polygon(x,y,len));
 
 
Would proj.forwardRaw speed things up? I tried to use proj.forwardRaw but
the results were a bit strange?
 
Area getArea(Projection proj)
{
          Point pt=new Point();
          for(int i=0;i<len;i++) {
            proj.forward(lat[i],lon[i],pt);
            x[i]=pt.x;
            y[i]=pt.y;
          }
          return new Area(new Polygon(x,y,len));
}
 
Thanks
 
Simon
