title: JMeter: Stepping Thread Group vs Concurrency Thread Group - why newer is better?
body: <p>I've done web search for <code>site:stackoverflow.com JMeter: Stepping Thread Group vs Concurrency Thread Group</code> and have not found much. 
  On <a href="https://jmeter-plugins.org/wiki/SteppingThreadGroup/" rel="nofollow noreferrer">https://jmeter-plugins.org/wiki/SteppingThreadGroup/</a>:</p>
  
  <blockquote>
    <p>Stepping Thread Group This plugin is deprecated and should not be
    used. Use Concurrency Thread Group instead.</p>
    
    <p>However, time goes by and probably better alternative has been
    offered: Concurrency Thread Group</p>

  <p>I've used <code>Concurrency Thread Group</code> and just found about <code>Stepping Thread Group</code>. As I've seen deficiency of <code>Concurrency Thread Group</code> is that is does not do (and no options for) ramp-up for steps.</p>
