title: Jmeter Response Times vs Threads
body: <p>I am doing API load testing by sending 250 requests at once.</p>
  
  <p><strong>1. Configuration</strong></p>

  <p>Naturally, server takes longer to respond when a lot of users requests it simultaneously, this is what it says here.. As per <a href="http://jmeter-plugins.org/wiki/ResponseTimesVsThreads/" rel="nofollow noreferrer">http://jmeter-plugins.org/wiki/ResponseTimesVsThreads/</a>.  However when testing this is what I found..</p>
  
  <p><strong>2. Test</strong></p>

  <p>The plot above starts from right to left and as the number of active threads decrease, the response time increases.</p>
  
  <p>Is <strong>active threads</strong> same as <strong>number of user requests</strong>, if so why this is happening on a consistent basis?</p>
  
  <p><strong>Update-1</strong>
  Ran another test and increased the ramp-up period this time</p>
  
  <ol>
  <li>No of threads: 200</li>
  <li>Ramp-Up Period: 200 secs</li>
  <li>Loop Count: 200</li>
  </ol>
