Bad Performance on handling big design document tree with consist render updates

[softmarshmallow]

As you can see we’ll need to handle design document tree handling on a C++ Bridge
I’m not quite sure what causes this major performance down break

Write Design Document Tree Parser (IO) based on C++
On this level, React (App) will only provide full Design document tree initially, givving only the command events. (E.g. On Dragging, App will only provide the pointer event and everything else will be handled inside c++ bridge)

I've referenced this to README's roadmap
