Thanks for the hints, Andrea.If we provide fixed values for time and spatial extent when creating the layer - would that avoid the execssive data base queries?

We are operating a geoserver instance that has about 600 time-enabled vector layers (loaded from a postgres database) which causes two problems: 1) The capabilities take a very long time (>5 Minutes) to load 2) The capabilities are becoming quite big (Currently about one 1MB) so we might run into issues with clients So are there any solutions for these problems? Can we speed up the Capabilities response? Can we maybe assign layers to different WMS endpoints? You should probably partition the stores/layers in different workspaces, and use the worskpace specific OGC services. The other thing that slows things down is that for each time enabled layer a query is done against the database to retrieve fresh time values... we don't have a way to register them statically, but I'm thinking that one potential improvement to GeoServer (which requires coding) could be to submit these lists to some caching, so that they are not requested every time (pretty much like we cache the structure of feature types today).... the significant downside of this approach is that the list of times can be very large, caching it would eat memory easily...
