I will strongly recommend that nobody does. First: _maybe_ relevant and competent benchmarks will _eventually_ vindicate one or the other approach, but in all likelyhood, the difference is a wash for all real-world, practical purposes. Second: nobody is going to convince anybody about anything on a topic where the fronts have been drawn up so sharp from the beginning. Time spent on tilting windmills is time not spent on the code. Third: Linus has internal project fights to fight, and this could quite likely be part of internal Linux bickering that got out of hand. If any kind of official response should be generated, it should be humorous and mostly non-insulting. Something like: The FreeBSD Project has taken Linus recent comments "ad notam". We usually hold Linus' technical competence and judgement in high regard, but if we are indeed "incompetent idiots" people should really not trust us on that point. would do fine.
