Do you spliited the polygons manually or you have some script ? perhaps using gdal ?<br><br><div class="gmail_quote">On Wed, Oct 27, 2010 at 1:36 PM, Rahkonen Jukka <span dir="ltr"><<a href="mailto:Jukka.Rahkonen@mmmtike.fi">Jukka.Rahkonen@mmmtike.fi</a>></span> wrote:<br>

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.</span></font></div>

<div></div>Hi All,
<div><br></div>
<div>I have a shape with 2M polygons. The biggest one has 13k points. It works
very well, and fast enough.</div>
<div><br></div>
<div>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</div>
<div><br></div>
<div>Is there a maximum number of points for single polygon supported by
MapServer ?</div>
