I said nothing about Ractive and Vue. Their 2 way binding is better, but with large quantities of bindings, it's still slow.

Virtual dom consume more computation processor while data binding consume more memory.

...In theory, but IIRC, binding doesn't cover all the types of updates that vdom does, and vdom is better at avoiding thrashing.
