Mustafa,
I don't see why you absolutely need to have vector features. Like Phil
said, WMS is much faster. Since you're querying your features with a
click, doing so on a fast image with a WMS GetFeatureInfo request is
enough. The result shows after a very small delay, which is the only
downside but at least your navigation experience isn't affected by heavy
vector features the browser has to manage.
I'd strongly suggest that you use a WMS layer and use the GetFeatureInfo
control.
Kind regards,
Alexandre

Ok!, I see your example,
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);
