<div>thank you for the fast answer. What do you mean with 'optimize your data'? I'm trying to aggregate some feature in a layer, where it is possible, but I've got many data that I can't modify...<br>

Hi,<br>
<br>
It's a matter of data optimization. I suggest you to try to optimize your data and mapfile before continuing with Chameleon. The MapServer mailing-list will be the right place to ask question about that.<br>

Subject: [Chameleon] Map refresh slower at bigger scale<br>

Hi,<br>
I've got a Chameleon application that takes data from a big Postgis database<br>
(a dump of 300MB). My problem is that the refresh of the map takes much more<br>
time when I am at a bigger scale. For example with the same layer activated:<br>
-if I am at scale 1:100.000 and I zoom to scale 1:5.000 the refresh takes<br>
more or less 10 seconds<br>
-if I am at scale 1:5.000 and I zoom to scale 1:1.000 the refresh takes<br>
around 30 or more seconds (it depends on the number of object in the area)<br>
What I would like to understand is why there is so much difference in the<br>
drawing time of this two maps. Why is the second dwawing time greater then<br>
the first drawing time? I was expecting exactly the contrary, is it normal<br>
or is there something wrong in my mapfile or somewhere else?<br>
<br>
Do you know what I can check to solve this problem? And can you suggest me<br>
how I can make my application faster?<br>
Thank you all in advance.<br>
Federica<br>
