It is unfair to say that yaws does not perform like misultin and I do not have data to make that statement.  When I think of performance, I am also thinking of software development performance for modifying, extending, and using the code-base.  Yaws has lacked support once mochiweb was available because of some fragmentation within the community.  From what I have seen, yaws chooses not to focus on performance, and has never intended to do so in the past, so it is unclear whether it would be able to maintain its performance in the future, if it received more support (based on http://steve.vinoski.net/blog/2011/05/09/erlang-web-server-benchmarking/).  So, that was misleading for me to say, since you are probably correct that misultin is on par with yaws, though there are no public results to show that.  With yaws the concern seems to be more about the code being regarded as legacy, not actively developed, and not modular (and whatever other reasons that seemed to make mochiweb
appear necessary).  I say this knowing that you are currently the main maintainer of the code-base.  These are just the impressions I have had from being within the Erlang community for a few years.
