If I zoom in very close, I can hardly pan at all - the map simply does not respond to my click+drag motion. I am restricting to 20,000 the number of points fed to the clusterer (because of this limitation), but would like to allow millions. Is there any way to improve this behavior? Or is it inherent to the way the clusterer is implemented?</SPAN></BODY></HTML> Mon, 04 Jun 2012 20:19:10 GMT https://community.esri.com/t5/arcgis-api-for-silverlight-questions/panning-performance-suffers-when-using-clusterer/m-p/400485#M10408 NathanielWingfield 2012-06-04T20:19:10Z Re: Panning performance suffers when using clusterer https://community.esri.com/t5/arcgis-api-for-silverlight-questions/panning-performance-suffers-when-using-clusterer/m-p/400486#M10409 <HTML><HEAD></HEAD><BODY><SPAN>Cluster or not, for performance reason,&nbsp; you can't render 1000000 points at client side.</SPAN><BR /><SPAN>Please look at this thread </SPAN><A href="http://forums.arcgis.com/threads/28815-How-to-display-1-million-points-in-the-Map">http://forums.arcgis.com/threads/28815-How-to-display-1-million-points-in-the-Map</A><SPAN> that might help.</SPAN></BODY></HTML> Tue, 05 Jun 2012 05:47:43 GMT https://community.esri.com/t5/arcgis-api-for-silverlight-questions/panning-performance-suffers-when-using-clusterer/m-p/400486#M10409 DominiqueBroux 2012-06-05T05:47:43Z Re: Panning performance suffers when using clusterer https://community.esri.com/t5/arcgis-api-for-silverlight-questions/panning-performance-suffers-when-using-clusterer/m-p/400487#M10410 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Cluster or not, for performance reason,&nbsp; you can't render 1000000 points at client side.<BR />Please look at this thread <A href="http://forums.arcgis.com/threads/28815-How-to-display-1-million-points-in-the-Map">http://forums.arcgis.com/threads/28815-How-to-display-1-million-points-in-the-Map</A> that might help.</BLOCKQUOTE><BR /><SPAN> </SPAN><BR /><SPAN>But is there any solution to clustering my 20,000 points?
