I would go for the former, GeoServer never loads the full data set in memory, it loads it in small chunks, renders/transform it, outputs the result, get another chunk and so on (we call it data streaming). It's normally not beneficial to give GeoServer more than 2GB of memory, unless the maps you need to build (in terms of pixel size) are really big. If you have lots of memory to give GeoServer better start two GeoServer in parallel and get more scalability, see this presentation for other suggestions: http://demo.geo-solutions.it/share/foss4g2011/gs_steroids_sgiannec_foss4g2011.pdf Cheers Andrea -- ------------------------------------------------------- Ing.
