<div dir="ltr">Hi,<br>I've got a Chameleon application that takes data from a big Postgis database (a dump of 300MB). My problem is that the refresh of the map takes much more 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 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 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 drawing time of this two maps. Why is the second dwawing time greater then the first drawing time? I was expecting exactly the contrary, is it normal 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 how I can make my application faster?<br>Thank you all in advance.<br>Federica<br></div>
