I see that HTMLBars is building more of Document fragments rather a single DOM tree. Would be interesting to check if all these document fragments are independent to each other like 1000's of HTMLBar views inserted directly into the Ember Application as siblings rather as a tree. There will be lot of memory involved than when you use a single DOM tree. isn't it?
