Hi,
I’m currently working with openlayers, postgis and geoserver building a site to serve maps with cross-layer filtering and other features (like drawing, uploading, etc.). Since we are expecting to get several clients using the service, we’re concerned with server performance and concurrent usage limit. We began to run some benchmark tests on this issue using wfs-t and geoserver vs direct postgis requests but haven’t been able to build equivalent requests for cross layer filtering using both methods (some of the requests return the same results and most of them don’t). My question is:
Is there any documentation on wfs-t implementation that would lead us to understand the difference with simple postgis databes requests?
