title: What is the purpose of Using "Ultimate Thread Group": need to know the practical usage
body: <p>Can some one explain what is the purpose of <a href="http://code.google.com/p/jmeter-plugins/wiki/UltimateThreadGroup" rel="nofollow">Ultimate Thread Group</a> considering it's practical usage. I am new to JMeter and as I've learned (please correct me if i am wrong), we use "Ultimate Thread Group" to time scheduling the ramp up/down time of multiple threads we create for a particular JMeter scenario script.</p>
  
  <p>I feel this also can be done using <a href="http://code.google.com/p/jmeter-plugins/wiki/SteppingThreadGroup" rel="nofollow">Stepping Thread Group</a> as well by having multiple threads attached to the same test plan. So i need to know exactly what is the significant usage of Ultimate Thread Group.</p>
