I would like to know , that if i get an array of polygons from db (assume constant) and match it with current map graphicslayer graphics geomtery, in that case how intersect will work. to match 2 arrays of geometries
don't it make my app very slow, to retrieve all users polygons(more than 1000) from db and then check on browser side with this method. one by one.
Is their any method to check it on server side.
As i have to show also that overlaped polygon, so i think it makes my app very slow
