title: What value of backlog should I use?
body: <p>I read the <a href="http://linux.die.net/man/2/listen" rel="noreferrer">man 2 listen</a>.</p>
  
  <p>I don't understand what is the backlog value, it says </p>
  
  <blockquote>
    <p>The backlog argument defines the maximum length to which the queue of pending connections for sockfd may grow</p>
  </blockquote>
  
  <p>Right, how can I define what is the best value?</p>
  
  <p>Thanks</p>
