Hi,
All I can say is that with our data the service went all to slow for the end
users long before jamming. We have been splitting the biggest lake polygons
into pieces with no more than 45000 vertises because that was the limit of
reasonable speed in our environment. But in that case the limiting factor was
the database and "contains" queries, not Mapserver. Anyhow, splitting the
lakes was good for Mapserver too. For some other layers we have made
simplified versions for the far-away zooms. Simplifying is better for WMS use
if polygons are drawn with different outline colour but it gives a bit more
work with building the scale dependent layers.

Aihe: [mapserver-users] Maximum number of points in a poligon
Hi All,
I have a shape with 2M polygons. The biggest one has 13k points. It
works very well, and fast enough.
I have another shape with 300k polygons and the biggest one has 800k
points... This shape hangs MapServer !... and I have to kill the process by
hand using kill -9. (see the other thread: process survive after killing
apache). The shape files can be opened with ogrinfo though
Is there a maximum number of points for single polygon supported by
MapServer ?
Thanks
