I am attempting to load a world map as a shapefile for users that are disconnected for the network. While I can do it, I have noticed it is extremely slow to render. If the map has to refresh due to a move or zoom, the CPU jumps up for 20 seconds or so before the map finally displays. Maps loaded over the network are loading significantly faster than a shapefile stored on my local hard drive. Is there something that can be done to optimize the performance of rendering a vector map? Right now I am loading it as a feature layer.
