JMeter max user limitation

In conclusion, we can say that you can simulate up to 10,000 users on a JMeter load test even on a regular laptop. This depends on following 4 simple rules:

• Use JMeter listeners for debugging purposes only
• Run JMeter performance tests in non-GUI mode
• Increase JMeter heap space to generate a larger load
• Use LAN instead of a Wi-Fi connection when running a load test

As you can see, the answer to the question ‘What’s the maximum number of users you can test on JMeter?’ varies. It depends on many factors: test complexity, script running method, internet and machine capabilities and so forth.

I have found the user limit on my local laptop is 8000-9000 users. But what if you need more? There are options to do that:

1. JMeter enables running scripts in distributed mode by using a few slave machines with your own main one, and then combining and outputting the results. With this method you can scripts horizontally without any limitations except for the number of slave machines you allocate for tests.
