How does remote testing distribute work?
I am setting up a 500 user test script, where 500 users are distributed in 5 thread groups(5 separate use cases) of 100 users each.
TestPlan
---TG1 (100users)
---TG2 (100users)
---TG3 (100users)
---TG4 (100users)
---TG5 (100users)
I have 5 remote servers configured in my jmeter properties to distribute my load on, and I have also registered my locahost ip. So RemoteStart menu displays 6 servers.
So the list looks like:
1. localhost
2. LoadGenSvr1
3. LoadGenSvr2
4. LoadGenSvr3
5. LoadGenSvr4
6. LoadGenSvr5
If I click on Remote Start All now, how will JMeter distribute the load on these 6 Load Generating nodes?
1. Will it execute the whole script on all 6 nodes - 500 users on each node = 500*6 = 3000 user load emulated on target server?
2. Will it execute 1/6 of 500 users on each of the 6 nodes, so that the total load emulated on the target server stays 500 users?
3. Is there a way to set affinity of threadgroups to remoteservers, so that I can say TG1 would execute on LoadGenSvr1, TG2 on LoadGenSvr2, etc?
Please help me understand.

Yes - assuming that the thread groups are not set to run
consecutively, and assuming that they run for long enough that all
threads are active together.

Yes. Try it and see (start with a much smaller number of threads).

Ok.. So in this case you are saying that it will put a load of 500*6=3000 users on the server?
Will the data collection reflect this total number on the controller jmeter machine (in the grpThreads or allThreads columns in the reports)?

In JMeter client-server mode, the JMeter client sends the same test
plan to ALL the servers which all run the same plan.
It does not do any load distribution or balancing.
