I need to add several vector layers at runtime.
All those layers are quite big but all of them have a <layout/>.
The 25 layers are added to the MAP through an osg event thus it is executed during the frame and it blocks the rendering.
The process takes 4 seconds, but i thought that using the layout mechanism the process would not block the frame (because i expected that all the process is sent to the DBPager thread).
So what is done when addLayer is executed, what can lead to 4 seconds?
