title: Jmeter- how do i know when i need to create new thread or user?
body: <p>I am a tester. 
  I went through Apache Jmeter. 
  I understood some features but still I have some doubts regarding its features. </p>
  
  <p>I am testing a web based application, which has number of web pages including log-in page.</p>
  
  <p>I need to do performance testing on it.</p>
  
  <ol>
  <li><p>I want to know when i should create a new user ?</p></li>
  <li><p>How number of loops affects the results?</p></li>
  <li><p>Should i run each HTTP request one by one or after creating all HTTP request i can run all requests at a time?
  (if i set loop=2, and create a HTTP request and click on run then result comes in 2 iterations &amp; when i create new HTTP request &amp; again click on run then i am getting result in 2 iterations for recent HTTP request &amp; for previous one it will be in 4 iterations
  but when i run all HTTP request at a time then get result for all HTTP request in 2 iterations only)</p></li>
  </ol>
  
  <p>I want to know that which process is right?</p>
