Server-side caching of WMS tiles is the best way to increase performance. In caching, pre-rendered tiles will be saved, eliminating the need for redundant WMS calls. There are several ways to set up WMS caching for GeoServer. GeoWebCache is the simplest method, as it comes bundled with GeoServer. (See the section on GeoWebCache for more details.) Another option is TileCache. You can also use a more generic caching system, such as OSCache (an embedded cache service) or Squid (a web cache proxy).

Caching is also possible for WFS layers, in a very limited fashion. For DataStores that don’t have a quick way to determine feature counts (i.e. shapefiles), enabling caching can prevent querying a store twice during a single request. To enable caching, set the Java system property org.geoserver.wfs.getfeature.cachelimit to a positive integer. Any data sets that are smaller than the cache limit will be cached for the duration of a request, which will prevent them from being queried a second time for the feature count. Note that this may adversely affect some types of DataStores, as it bypasses any feature count optimizations that may exist.
