Take the 2-minute tour ×  I have over 140 layers that need to
appear as overlays on basemaps(Google and OSM). My users can
pick and choose which layers they want to see and store them in
their preferences. While we have built the solution, the
performance is very slow. These layers get served with
openlayers making WMS calls to GeoServer and Postgres DB.  I
tried using GeoWebCache and Tilecache but then realized that
they are not all that helpful when I have dynamic layers. The
XML definitions of what layers to cache are static.  What are my
options here? Is there a way to cache such combinations, or do I
take a different route and investigate on HTTP caching with
tools like Varnish?  share|improve this question Please, could
give an explanation about what you to mean with 'dynamic
layers'? –  dariapra Aug 25 '12 at 19:47 Layers are features
that portray different aspects of a location. Here is an
example/ portrayal of various layers that collectively can be
overlayed on a base map thepiazza.org.uk/bb/viewtop
