[mapguide-users] performance difference between similar maps?

[Fritz Robert]

Hi,

I have two maps: – one contains only layers with cadastral information (approx. 30), the second one contains the same cadastral layers and additionally 500 other layers.

For my test the following applies:
Only the layers that appear in both maps are drawn, both maps reference the same set of layers. All other layers in map #2 are turned off.

When panning - let's say at 1:500 - the map with only  few layers is drawn much faster then the other one (600ms vs. 1200 ms).

I do not understand why this is. Can someone shed some light on this?
All layers and maps use one coordinate system.

Looking at Performance report all values nearly look the same except for category "Others"“:

Other ,"140.0050868988 ms",24.4% - map #1
Other ,"784.38530349731 ms",63.6% - map #2

What does „"Others"“ comprise of?

Regards, Rob
