title: I don't understand the Node.js architecture
body: <p>We are considering <code>node.js</code> as a web platform. But I have one crucial question, because I think I don't get the architecture of <code>node.js</code>:</p>
  
  <ol>
  <li><p>It looks like that by default you're forced to use their custom HTTP server, no WSGI or anything?!</p></li>
  <li><p>It looks like that when doing some "real computation" in a response (not only some I/O), all the infrastructure is messed up and <code>ab -n ... -c ...</code> returns enormous times per request compared with e.g. Python -- Pyramid/Flask or whatever?!</p></li>
  <li><p>So, authors of <code>node.js</code> assume that we're doing only I/O or I've missed something very basic?</p></li>
  </ol>
