title: Rabbit amqp connection takes too long time
body: <p>I've got very strange thing. Connection to my rabbit server takes 0.6 - 3 seconds ... </p>
  
  <p>AMQPConnection::connect() works really long time. At my dev and stage machines everything is ok, but on production under slightly highload (publish ~10 messages\second) i've got connections time trouble...</p>
  
  <p>How and where can i start my research about it? </p>
  
  <p>Thanks a lot.</p>
