Howto distribute outbound traffic in Jmeter

Question

how jmeter can distribute outbound traffic between the two user groups. For example the group #1 gets 30% of the traffic and the group #2 of 70%.

Answer 1

There are various ways you can do this. You could use a Throughput Controller which is pretty simple, or, if you only ever want one request to fire, you could create a simple Random Variable, set it as a random number between 0 and 10 and then use an If Controller to control execution.

Something like:

Thread Group
    - Random Variable 0 - 10
    - If Controller set to ${myVar} <= 3
        HTTP Sampler
    - If Controller set to ${myVar} > 3
        HTTP Sampler

Answer 2

Not sure I understand your requirement as Oliver did, for me you just setup a Thread Group with 30% of the total threads and the second one with 70%.

Otherwise, you can read this article with is another way to do the way Oliver understood:

It shows how to distribute but contrary to Throughput Controller it ensures at least one sample is executed.
