I saw some blog posts where people talk about JMeter and Docker. I understand that Docker will be helpful for setting up a container with all the dependencies. But they all run/create the containers in the same host. So ideally all the containers will share the host resources. It is like you run multiple instances of jmeter in the same host. It will not be helpful to generate more load.
When a host has 12GB RAM, I think 1 instance of JMeter with 10GB heap can generate more load than running 10 containers with 1 jmeter instance in each container.
What is the point of running docker here?
