How to avoid the problem of response data size limit in View Results Tree listener in JMeter 

1. View Results Tree is very useful listener especially when you are debugging your test plan. You can review the response data and ensure that your test plan works good. But sometimes you can see a message in the beginning of the response data like "Response too large to be displayed. Size: 313674 > Max: 204800, Start of message:" 

  2. And unfortunately you are not able to see the whole response data. By default JMeter  
       shows only first 200 Kb of response data.  
  3. To resolve this problem you should edit the file jmeter.properties and uncomment the
       line:             view.results.tree.max_size=0 
  4. After you have saved jmeter.properties you will never see this message again.
