How many users does jmeter support

But our goal is to check how many users JMeter can simulate. To do that we can just remove listeners and verify if the script can be run successfully with the same 1, users as the target load. We clicked the button and… This time I found the script failed while adding the th user:. JMeter GUI is wonderful when you need to create, edit and debug your tests, but is not a great solution for running created tests.

The same article mentioned before explains how you can run your tests in Non-GUI mode and save lots of resources to simulate a larger load. This is why it is highly recommended to run your load scripts in Non-GUI mode. By using that simple action, we can save lots of machine resources and avoid nasty memory issues. We are out of memory again. This time it happened after simulating 1, users. Can we move further? Of course the answer is yes! The JMeter heap has default limits that can be easily increased without any harmful effect for test execution.

Just open your JMeter runner script located in the JMeter bin folder and replace the value of max heap space which goes after -Xmx flag that has these default values:. All the previous test executions were performed while using Wi-Fi connection. The connection was working fine until this moment, but to go further we need to switch on the LAN internet connection.

This time the test passed without any issues. We can confirm that a regular laptop can simulate 2, users and we should now try to go for the next limitation.

We simulated JMeter for more and more threads. As a result, we found that the max value of users we could simulate was around users. Create a free Team What is Teams? Collectives on Stack Overflow.

JMeter lets you include that in the script see example. One of the tests required testing 1 million unique, 1 time use codes. In conclusion, we can say that you can simulate up to 10, users on a JMeter load test even on a regular laptop. This depends on following 4 simple rules:. 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 8,, users. But what if you need more? There are options to do that:. 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. You can also always use cloud solutions. BlazeMeter provides an easy-to-use cloud testing platform, enabling you to run as many users as you wish.
