title: JMeter, Jetty Performance test and Keep-Alive issues
body: <p>Ok, so I created a very simple WAR which serves a simple Hello World .jsp. With all the HTML it's about 200bytes.</p>
  
  <p>Deployed it on my server running Jetty 7.5.x jdk 6u27
  On my client computer create simple JMeter test plan with: Thread Group, HTTP Request, Response Assertion, Summary Report Client also running jdk6u27</p>
  
  <p>I set up the thread group to 5 threads running for 60secs and I got 5800 requests/sec
  Then I setup 10 threads and got 6800 requests/sec</p>
  
  <p>The moment I disable Keep-Alive in JMeter on the HTTP Request sampler. I seem to get lots of big pauses on the client side I suppose, it doesn't seem the server is receiving anything. I get less pauses at 5 threads or barely none but at 10 threads it hangs pretty much all the time.</p>
  
  <p>What does this mean exactly?</p>
  
  <p>Keep in mind I'm technically creating a REST service and I was getting the same issue, so I though maybe I was doing something funky in my service, till I figured out it's a Keep-Alive issue as it's doing it pretty much on a staic web app. So in reality I will have 1 client request 1 server response. The client will not be keeping the connection open. </p>
