Why would you expect it not to be?
Do you have timings to demonstrate this?
Are you trying to solve a performance issue? Or gain detailed knowledge of the product's internal parsing strategy?

So how much of a difference are you seeing? I'd not hae expected an impact unless you have a very large document or some very dodgy code.
The simple answer is that "set" requires the tree to be parsed where "create" does not require a full parse.

Is that a question or a statement?
