Apache JMeter is a Java application with a good UI interface, very easy to design new tests, however if you want to run load or performance tests you should run the JMeter test. This way you will be able to start a lot more concurrent threads. As an average you can start between threads on a single machine , with a maximum of threads.
Before starting the actual test, you need to do a dry run from the injector machine and inspect when the tests start failing and limit the maximum number of threads per thread group. To run a load or performance test with your own Apache JMeter script you can use Load Focus Cloud Load and Performance testing service which allows you to do the following:.

Because I assume if hardware is busy, some of the threads might not start immediately? Add a comment. Active Oldest Votes. 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 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.
