I see, thank you. I can succesfully return a WFS Version 1.1.1 request using
outputformat=GML2.
http://localhost:8080/geoserver/wfs?request=getfeature&version=1.1.1&service=wfs&typename=store:layer&CQL_FILTER=ADDRKEY=12203&outputformat=GML2<http://208.64.19.130:8080/geoserver/wfs?request=getfeature&version=1.1.1&service=wfs&typename=Sun:AddrPts_City&CQL_FILTER=ADDRKEY=12203>
However, it does not increase the performance of the V1.1.1 request - the
request still takes 20 seconds. As a matter of fact, i can use a Version
1.0.0 request to use GML3 and the request is still 300% faster.
http://localhost:8080/geoserver/wfs?request=getfeature&version=1.0.0&service=wfs&typename=store:layer&CQL_FILTER=ADDRKEY=12203<goog_32689416>
&outputformat=GML3
<http://localhost:8080/geoserver/wfs?request=getfeature&version=1.0.0&service=wfs&typename=store:layer&CQL_FILTER=ADDRKEY=12203&outputformat=GML3>
So what else could be the reason that a Version 1.0.0 request is so much
faster (300%), because it doestn appear to be the GML encoder...
