title: JMeter: Run 300 concurrent requests per second
body: <p>I have started 300 requests per second by providing following values:
  Number of Threads : 300
  Tamp-up : 0
  But I am getting following results:</p>
  
  <pre><code>summary +     55 in    21s 
  summary +    225 in  31.1s 
  summary =    280 in  31.1s
  </code></pre>
  
  <p>what different configurations would be needed to start all requests in one go?</p>
