I am using:- - windows10, - processor: Intel Core i3@2.00GHz, - RAM:8.00GB, - 64- bit OS. - jmeter 4.0

the scenario is I have to pass/send a request for JSON data in Jmeter body. I have to pass/send request of 50mb JSON data in the JMeter body.

But the problem is when my JSON data size more than 700kb, after that my system has freeze/not responding.

So, how can I pass/send request of JSON data size from 700kb to 50mb in JMeter with a single Request?

  1. Make sure to run your test in command-line non-GUI mode
  2. Make sure to increase JVM Heap Size so your file will fit into memory given the number of threads you're going to use multiplied by file size plus ~1 GB for JMeter to operate.

  3. Follow recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure, especially:

    • don't use any Listeners
    • don't save request/response data
  4. You can also consider using HTTP Raw Request plugin which is capable of sending files to the server without loading it into memory first.
