[Users] FeatureStore - too many features

Any hints on this?
Am I right to think that if I use BBOX with my wfs that my linked FeatureStore 
is only loading such number of features?
And why did including ext-override-ajax.js not work? 

Thanks!
best regards

Hi list,

I have a wfs and want to publish my data via a FeatureStore. 
If I load it with:
fields: [{name: .....}],
proxy: new GeoExt.data.ProtocolProxy({
    protocol: new OpenLayers.Protocol.WFS({
        url:
        ...
    })
})
there is a long loading time because of high number of features.
 
If I want to use 
layers: wfsLayer 
instead of protocol option (because I use BBOX filter for wfs reducing features 
from 10000 to some hundred) I get an error that proxy is undefined.
My wfs layer is:
wfsLayer = new OpenLayers.Layer.Vector("mywfs",
    {styleMap: wfsStyle,
      displayInLayerSwitcher: false,
     strategies: [new OpenLayers.Strategy.BBOX()],
     protocol: new OpenLayers.Protocol.WFS({
        featureNS: "myNS",
        featureType: "mylayer",
        version: "1.1.0",
        ...
        })
    });
I included a proxy script which is working.
I searched and found that I have to add ext-override-ajax.js to my GeoExt build 
but that did not help.

What I`m doing wrong?
Any hints to get better performance for displaying data?

Thanks
best regards
Sarah
