title: Python multiprocessing based WSGI webserver
body: <p>I am currently hosting REST webservice based on Bottle/Paste combination. However the application starts choking when there are about 50 concurrent threads. </p>
  
  <p>Paste uses multi-threading and hence limited by the GIL.</p>
  
  <p>I am planning to use CherryPy-WSGI server. My question is, does it use multi-threading or does it use multi-processing ? 
  Also can I use it with Bottle ?</p>
  
  <p>Environment :</p>
  
  <ul>
  <li>CPython 2.7</li>
  <li>Bottle + Paste</li>
  <li>Win server 2003, 4 core CPU</li>
  </ul>
