Hi, today I took some time to evaluate how much slower the new feature model is, compared to the old one.
I did run a couple of simple wms rendering tests against a 400MB roads shapefile, and against the same layer in postgis. Here are the results: GeoServer 1.6.x, shapefile: 4 seconds GeoServer 1.6.x, postgis: 46 seconds GeoServer trunk, shapefile: 7 seconds GeoServer trunk, postgis : 78 seconds Well, besides the fact the postgis is not really recommendable if you want to render a huge layer at once (instead of accessing small parts of it or doing attribute filters on it), the conclusion we can draw is that rendering got almost twice as slow. Profiling confirms all the extra time is spent in the SimpleFeatureBuilder. Optimizations aren't obvious either, I just tried a couple of obvious improments and the result is that the postgis rendering time went down from 78 to 72 seconds... It seems recovering from this hit will require some time and dedication.
