Right,
If it's only a click, using a WMS GetFeatureInfo request would be enough
though. You could always put a marker at the clicked location if you
wanted to keep track of where the user clicked. If you want to do a
"box" query, go with the WFS GetFeature control instead.

Mustafa646,
I think this was said before, but I'll try explain better. What you want to do
is change to using a WMS layer to display these features, and then on click do
a WFS call to get the feature info to display. The display of the features will
take a little bit longer but your app with be usable.

With the help of code below, i draw WFS Layer (3500 features) over google
map. But it takes so much time to draw completely, and my explorer freezs
some time. But the code works fine with small files like (200 features).
Actually i want to identify some specific feature under Button click event
by passing that feature's attribute value through textbox. For that reason,
i need to display Vector Layer (consists of 3500 polygon features) over
Google Map.
I search a lot, but could not find a way, how i can make it fast ?
need help !
code:
wfs = new OpenLayers.Layer.Vector("Data", {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
url: "http://localhost:8080/geoserver/wfs";,
featureType: "traget_grave3",
featureNS: "http://www.openplans.org/TestSpace";,
srsName: "EPSG:900913",
version: "1.1.0",
isBaseLayer: false,
visibility:true
})
});
map.addLayers(wfs);
