[OpenLayers-Users] Performance Issue with multiple layers

[Marc Desharnais]

Hi all,

I don't know if it's normal, but my page using 7 layers is really slow. 
I have to mention that the layers are not all activated. Only 2 of them 
are shown of on the map.

Initial loading takes up to 30 seconds. Zooming to a particular area : 
10 seconds.
And the CPU consumption of my workstation jumps up to 80% when loading 
times. Is this normal?
Logically the workstation should not work really hard since it is 
querying some PNGs... Am I wrong?

No server is on my workstation. The server and all the data used in the 
layers is on LAN.

6 layers are colored points and one is a shapefile converted to postgis.

What is slowing down the process?


Thank you :)
