IE 11 slows to a crawl with jsapi app

I have an arcgis js application heavily using esri.layers.GraphicsLayer s to display enterprise data (ASP.NET MVC Web API backend).  I am troubleshooting poor performance for IE 11 vs Chrome or Edge.  The IE 11 environment slows down after a few dozen map operations whereas Chrome and Edge are fine.  The app has multiple concurrent instances of esri.Map in separate UI panes.


My question is not whether IE 11 sucks - but rather are there any performance-related tweaks, configuration or coding techniques to help IE 11 along? 


Thanks, Bill
