I check in the How much data for map blog, I have about 220 polygons which have highly detailed Vertexes.when i used the application and tried to draw ploygon for 2000 polygons it worked .But problem i cannot compare vertex of my map with one in the example, My shape file is about 7mb is this too much.

I also made use of maxallowableoffset , performs improved but my browser still hangs.Can you please suggest some more ideas where i dont have to load feature layers intially and then load the features of map on user click.
