Hey Namaskara~Nalama~Guten Tag
I speak only from my experience of performance testing of over 100 applications. I am yet to come across a situation where the master-slave traffic would be so significant that it would cause a network bottleneck and would be greater than the client-server & server-server traffic More so, it is simple logic & would defeat common sense if the master slave traffic is more than the other network traffic in the system. Anyways, as i mentioned earlier, it would be great if practitioner would post actual scenario results. We would then be able to catch the snake from the scruff of the neck.
