One interesting observation is that in 5-node scenario with 2500 users which means 500 users/node, response time is same as that of {1,2,3,4} clusters (~100ms). But when I increase the users from 2500 to 2800, response time goes ~6 seconds. I stop tests when it goes above 6 seconds. In {1,2,3,4} nodes configuration, response time increases gradually.
