title: Which Python library should I use? SocketServer or Asyncio?
body: <p>I am going to create web server which could receive a lot of connections. These 10000 connected users will send to server numbers and server will return these squared numbers to users back.
  10000 connections are too many and asynchronous approach is appropriate here.
  I found two libraries for Python 3.4 which can help:</p>
  
  <p>socketserver
  &amp;
  asyncio</p>
  
  <p>With socketserver library we can use ThreadingMixIn and ForkingMixIn classes as async handlers. But this is restricted by number of cores.
  On the other hand we have asyncio library. And I don't understand how exactly does it works.
  Which one should I use? And could these two libraries work together?</p>
