Tip #15: Hacking the response data size limit

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 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:".

JMeter - Response too large to be displayed

And unfortunately you are not able to see the whole response data. By default JMeter shows only first 200 Kb of response data. To resolve this problem you should edit the file and uncomment the line:
 This will disable response data size check at all.

Uncommented view.results.tree.max_size=0

After you have saved you will never see this message again.

The problem with the response data size limit has been resolved.
