Idea: benchmark for vdom

What is the tradeoff between using a virtual document object model and straight-forward updating of the dom directly?  Surely, an app that inserts a single div in response to user input wouldn't justify the use of a virtual dom . But what is that tipping point?  What has to happen in the app in order for a virtual dom to become worth the engineering?

Perhaps a benchmark test could start with comparing two apps.  One using a virtual dom, the other not, but otherwise the same.  Compare metrics like time difference when inserting one element per cycle.  Then ten.  Then 100.

This might help:
