title: Deciding whether to use ws or wss?
body: <p>I have an account with a trading exchange and they have a websockets API which supports ws://... and wss://...</p>
  
  <p>For the non-authenticated channels such as the current state of the orderbook, is it an easy decision to just use ws, mostly for the (however minimal) time savings? Obviously I would like to have my data as recent as possible. </p>
  
  <p>I just want to check there's not some other factor which is more important than a few TLS encryption CPU cycles and ms in latency saved.</p>
