Dynamic fields, once they are actually _in_ a document, aren't any different than statically defined fields. Literally, there's no place in the search code that I know of that _ever_ has to check whether a field was dynamically or statically defined.
AFAIK, the only additional cost would be figuring out which pattern matched at index time, which is such a tiny portion of the cost of indexing that I doubt you could measure it.
