Re: [Geoserver-users] wfs getFeature request performance

Hi,
 
GetCapabilities is listing all the supported formats. Your list is probably like this
 
<ows:Parameter name="outputFormat">
<ows:Value>text/xml; subtype=gml/3.1.1</ows:Value>
<ows:Value>GML2</ows:Value>
<ows:Value>GML2-GZIP</ows:Value>
<ows:Value>SHAPE-ZIP</ows:Value>
<ows:Value>csv</ows:Value>
<ows:Value>gml3</ows:Value>
<ows:Value>json</ows:Value>
<ows:Value>text/xml; subtype=gml/2.1.2</ows:Value>
</ows:Parameter>

	Thanks Justin. 

	Yes, it is a point file of over 25,000 points. I was just shocked to see how much faster a WFS version 1.0.0 request was, even with the same high number of features. Seems like a step backward to me.

	Anyways, is there a way to specifically request a gml2 encoded file back from a WFS 1.1.1 request?

	thanks,
	-jl

		Yes, the gml3 encoder is much much slower than the gml2 encoder. 

		How many features are being returned for these requests? For a small handful of features i would not see too much of a difference but as the number of features increases the more of a hit you will see.

		It is a known issue and a while back I implemented some experimental stuff to make the gml3 encoder as fast as the gml2 one. But it is currently sitting on a branch... i hope one day to have the time to bring it back.

			Does anyone know identical WFS feature requests would take 20+ seconds using v1.1.1 and only 7-8 seconds using v1.0.0?  

			here is the simple filter request for example:
			http://localhost:8080/geoserver/wfs?request=getfeature&version=1.1.1&service=wfs&typename=store:layer&CQL_FILTER=ADDRKEY=12203 <http://208.64.19.130:8080/geoserver/wfs?request=getfeature&version=1.1.1&service=wfs&typename=Sun:AddrPts_City&CQL_FILTER=ADDRKEY=12203>
