title: How many concurrent clients locust support on each slave?
body: <p>I'm getting my slave processes killed when running more than 300 clients per node.
  The machines are hosted in Rackspace and the configuration of each one is:</p>
  
  <ul>
  <li>512MB RAM</li>
  <li>1 CPU</li>
  </ul>
  
  <p>Should I increase the memory of the machines?</p>
