Base Map and ZoomTo Slow Performance with Clusters

Discussion created by glaitman on Mar 27, 2014
In my .net development environment, I have implemented the Clustering described in this sample: https://developers.arcgis.com/javascript/jssamples/layers_point_clustering.html
It is working fine. However when all the records (7,500) are loaded and I zoom to a location, the base map (Streets) takes about 45 seconds to render. When I filter the records so only 1,000 are clustered, the zoom to location the base map loads in less than 2 seconds. Any ideas on how to reduce the time it takes for the map to render when all records are loaded?
