Nah, your spiral is still in the sane zone. A few days ago someone on
GeoServer user list complained its 100MB shapefile
was slow to draw (and 100MB is not that much) so we checked, it contained
only 5 geometries, here is a query
returning the number of points from each of them:
> select st_npoints(geom) from puffer;
st_npoints
------------
183783
538938
709089
933145
3213841
1127425
Want insane? Try 3 million points like in the second to last geometry :-)
Cheers
Andrea
PS: GeoServer will clip and simplify the geometry before throwing it at
java2d, exactly because we know
java2d is not so good at handling this kind of complexity
