Since Lucene is schema-less, my assumption would be that using dynamic fields wouldn't have any effect on performance within the search stack itself - presumably the only penalty would be matching a given field name against the appropriate dynamic field (which I would assume would be cached/memoized). Lots of assumptions there, of course. Feel free to correct me if I'm wrong.
