[OpenLayers-Users] loading heavy WFS. solutions?

[David Fawcett]

Have you thought about creating several versions of your polygon data?
 Essentially, the vector pyramids that you were talking about.    Keep
your very detailed layer and then create several, increasingly more
generalized layers.

Set up a WFS or WMS using MapServer.  For the MapServer layer that you
are serving, create a class for each of the data sets and then make
them scale-dependent using MAXSCALEDENOM and MINSCALEDENOM so that
each data set shows up at the appropriate scale and only one data
source shows up at a time.
