title: How to send concurrent requests in Jmeter
body: <p>I want to use Jmeter to capture response times for requests to my web script in a concurrent way, but Jmeter sends them sequentially.  Is there any way I can simulate concurrent requests?</p>
  
  <p>I'm looking for something similar to <code>web_concurrent_start()</code> in <a href="https://software.microfocus.com/en-us/products/loadrunner-load-testing/overview" rel="noreferrer">LoadRunner</a>.</p>
