Slow performance is observed when rendering PictureMarkerSymbols with a unique value renderer on a map service.

解决办法

1. Create a feature layer using the sublayer from the map service. 
2. Set the renderer from the map service to the renderer of the feature service. 
3. Add the feature layer to the map. This allows for the picture marker symbols to load faster.

The following is a sample JSBin workaround: https://jsbin.com/tucisoyode/edit?js,output.
