[OpenLayers-Users] Why WFS Layer Displayed very slowely over Google Map

[Charles Galpin]

Mustafa646, 

I think this was said before, but I'll try explain better. What you want to do is change to using a WMS layer to display these features, and then on click do a WFS call to get the feature info to display. The display of the features will take a little bit longer but your app with be usable.
