Dynamo Makes for a Slow 2016?

Might have something to do with our computers, but when I use Dynamo (particularly a large, and somewhat complex definition) it brings Revit to its knees. I have to close Revit and reopen to get things back to normal. Anybody else experiencing this? What might be the cause?
