FeatureLayer load performance

EdwardSon

Is there any other performance improvement technique avaiable?
Using OnDemand with OnDemandCacheSize = 1000.
Also setting the MaxAllowableOffset based on map resolution on map resolution changed.
For some of the layers this really improved performance.

Still would like to increase feature retrieval/update performance for some of the layers (particularly those composed of lines).  In particular becuase now have to do update each time the resolution changes.

It seems like the silverlight application builder uses some additional optimization techniques.
If the layer are added using the builder the layers load instantaniously, but they don't exist as featurelayers, but rather as layerinfos in the Current.Map.Layers structure.
Is it possible to leverage additional optimization techiniques.  We need the layers to load instantaneously; it's taking about 6-10 seconds each time the map resolution changes.

See this thread for a possible workaround to avoid the Update().

Else as gigemboy mentionned, you'll get the best performances by using a DynamicMapServiceLayer or even better with a TiledMapServiceLayer (images cached at the server side).
