title: Can i set ramp up period 0 in JMeter?
body: <p>I am doing performance load testing in a web based application. </p>
  
  <p>I learnt from JMeter Tutorial that how can I set the Ramp Up period,
  eg:</p>
  
  <p>If 10 threads are used, and the ramp-up period is 100 seconds, then JMeter will take 100 seconds to get all 10 threads up and running. Each thread will start 10 (100/10) seconds after the previous thread was begun. </p>
  
  <p>10 users, 100 seconds ramp-up - start with 1 user, each 10 seconds 1 user added</p>
  
  <p>but I have one doubt can we set Ramp Up period 0 ? if yes,then How result will be affected by 0 ramp up?</p>
