Hi,
I was doing some tests regarding the performance issues reported by a user
in WFS 1. and WFS 2.0 and while at the moment I could not replicate those
results (which related to the time it takes before the first result comes out of
the WFS), I’ve found some worrysome performance results nevertheless.
Look here, same request, different protocol (even forced the output SRS to make
sure WFS > 1.0 is not reprojecting the data):
curl “http://localhost:8080/geoserver/nurc/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=nurc:buildings&BBOX=11.386153034926789,47.913610526723836,11.852600617836472,48.30077117627526,EPSG:4326&srsName=EPSG:4326” > /tmp/gml20.xml

Ah hem… the WFS 1.0 output is over 10 times faster than the WFS 1.1 and WFS 2.0
ones?
When five years ago I’ve reported the WFS 1.1 slowness issue the difference
was “just” 5 times:

Any clue about what might have happened in the meantime?
Cheers
Andrea
