If you are on the localhost it's normal, a 500MB shapefile will turn into several GB of GML that geoserver has to produce and qgis to parse, so they will both use a lot of CPU during the data transfer. The bigger the file, the longer it will take to generate and parse all the GML As a term of reference, I have a line shapefile that is 80MB (just the shp), extracted it in GML form (getting just the geometry attribute), the my core I7 860 stayed above 80% for 6 seconds and generated a GML file that was 304MB. Add something that has to parse the GML on the other side and your CPU usage is surely going to go up a lot I've just tried to add that layer to qgis, both geoserver and qgis both stayed at 100% for 8-10 seconds, but then geoserver finished its part and qgis went on at 100% for 3 minutes, and then nothing showed up on the screen Cheers Andrea -- ------------------------------------------------------- Ing.
