What are practical performance limitations of self-hosted owin/Nancy web server?
<p>It is pretty clear that if you are developing a web UI for a desktop/server application owin/nancy hosting is a logical choice. It is also clear that for high traffic web site that would not be sufficient, but IIS hosting is preferable.</p>

<p>I would like to know what are the practical considerations / limitations when using self-hosted web app. Let's assume that we do not need any IIS provided <em>functional features</em> such as, say gzip compression. From pure performance point of view, at which load level (approximately) self-hosting starts breaking down, and why? Does IIS do thread scheduling more efficiently then owin host?</p>
