title: Standalone Python web server and/or nginx
body: <p>So I've done some reading about Python web frameworks (or servers?), mostly <a href="http://www.tornadoweb.org/" rel="nofollow">Tornado</a> and <a href="http://bottlepy.org/" rel="nofollow">Bottle</a> but also <a href="http://www.fapws.org/" rel="nofollow">FAPWS3</a>, and there are still some grey areas.</p>
  
  <p>First, these three web frameworks are all said to be fast, yet they all include a web server written in Python (except FAPWS3) which should be put behind nginx/Apache. Isn't this reducing the performance? I mean, we know that Python is much slower than C, why not only use nginx, or at worst, only the included Python web server?</p>
