Setting Number of Threads in Distributed Testing in JMeter

Question

I have to test an application with 1000 Users. For that, I have set up a load testing environment with 20 machines. Each Machine will generate a load of 50 VUsers.

So, I need a confirmation that the number that I will enter in ' No of Thread (Users) ' will be generated by all the slave machines. In my case, I should enter 50 and not 1000 here.

Answer 1

When running in a distributed testing (master/slaves) environment, you have the option of configuring the slaves differently. You start JMeter on the slaves manually, and then use the master to tell the slaves when to start sending requests to the server(s) being tested. This JMeter document describes the distributed testing environment pretty well.

In your case, it sounds like you want the slaves to behave about the same, so setting the number of threads to 50 for each of the 20 slaves is the correct thing to do.
