How do i distribute 100 users in distributed mode using jmeter with 3 slaves and 1 master machine?

Lets say, we have 100 users to performance load test using distributed testing user jmeter. How do I distribute these load among 3 slaves and 1 master machine?

Solution

  • By default each JMeter slave executes the Test Plan transferred from. master individually and independently.

    So if you have 100 threads (virtual users) in the Thread Group each slave will kick off 100 users and actual load will be 300 users.

    If you have 100 users in total you could

    • go for 33 users in the Thread Group and get 99 total users

    • or define the number of users in the Thread Group via __P() function like:

       ${__P(users)}

      this way JMeter will read the number of users from users property. In this case you can put the desired number of users into user.properties file on each slave like:

      • on slave 1 put users=10 and it will kick off 10 threads
      • on slave 2 put users=50 and it will kick off 50 threads
      • on slave 3 put users=40 and it will kick off 40 threads

      amend the numbers according to your needs.
