Hi, It is not unknown to have slow counting in PostgreSQL: https://wiki.postgresql.org/wiki/Slow_Counting and https://www.cybertec-postgresql.com/en/postgresql-count-made-fast/ I always try to avoid using the count-parameter, as the implications don’t seem user-friendly to me.

That say, it is possible to deactivate the number matched count on the layer configuration page unter the publishing tab: https://drive.google.com/file/d/1mx_1fPVJAu9ElgOcVwuXfOq30n6ONmKw/view?usp=sharing Hope this helps, Nuno Oliveira On Tue, Jun 1, 2021 at 2:44 PM Marcin Grudzień <mgrudzi...@gmail.com<mailto:mgrudzi...@gmail.com>> wrote: Hi, I have published INSPIRE Land Cover WFS service using Geoserver 2.19.1 with app-schema extension. The service is available at https://mapy.geoportal.gov.pl/wss/service/wfsLCV/guest?service=WFS&request=GetCapabilities The data is stored in the PostGIS database. The service publishes over 6 000 000 land cover objects. I noticed that it takes around 20 seconds for the service to return the response to the most basic GetFeature request https://mapy.geoportal.gov.pl/wss/service/wfsLCV/guest?service=WFS&request=GetFeature&version=2.0.0&TYPENAMES=lcv:LandCoverUnit&count=1 However, if I add the BBOX parameter to the request, significantly limiting the area of the request, the response times are much better. E.g. https://mapy.geoportal.gov.pl/wss/service/wfsLCV/guest?service=WFS&request=GetFeature&version=2.0.0&TYPENAMES=lcv:LandCoverUnit&count=100&BBOX=500000,500000,600000,600000 takes around 2 seconds. I suspect that such GeoServer behaviour is related to the fact that the server wants to establish the total number of features that can be downloaded by the service (attribute numberMatched) and is doing it for the full BBOX defined for the lcv:LandCoverUnit feature type in the service GetCapabilities response. I would be grateful for any suggestion regarding lowering the response times for the non-spatial GetFeature requests.
