KML loads very slowly in ArcGIS online

[BenjaminHarper]

I have a kml feed going into an ArcGIS online map that takes nearly 8 seconds to load. Any suggestions to optimize for speed? Ultimately, the map is being consumed/viewed in a gallery, but is slow on arcgis.com as well. See http://www3.multco.us/maps/district2gallery  ...the "Out and About" map is the culprit.

Thanks much for any assistance!

Does anyone at ESRI have a reponse? Other folks with the same issue?

Thanks much,

It does seem a little slow. We'll have to investigate and see if we find anything.

Thanks,

This KML file defines two identical styles, which is causing the slowness. We've made some optimizations that will (probably) go out when we next update the website. If you can adjust your KML, that may help in the meantime.
