HI all ,I create a point FeatureLayer which contains perhaps 450 Features,after that ,I load a basemap and this FeatureLayer in my browser. when i zoom or pan the map,the map can not move  smoothly,the user experience is very bad.
the samples http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/#sample/widget_gauge ,its FeatureLayer contains 406 Features,however it can be operated without any delay and very smoothly.

Please HELP!
