Hi, We have a polygon layer used as a backdrop for a WMS based layer group. The layer contains the outlines of the UK, one of which is the mainland and is obviously quite large. I have generalised versions of the geometries to use when zoomed out, however when zoomed in, encoding the whole mainland for every tile introduces a bottleneck and requests quickly build up and time out as every request. The layer group contains around 20 different layers, without the polygon layer the group renders very quickly add the layer back in and it becomes very unsresposive.
The layer is used to provide the coast and a background colour for land. I'm looking at "chopping" up the polygons on a grid to create smaller geometries that can be used to provide the background colour and extract the coast into a number of smaller lines. But before I do this I was wondering if there was some way I could get geoserver to cache the features for this layer in memory rather than having to hit the database for every request.
