Initially i have tried with same 100 concurrency and the results are almost
identical. That is where my doubt started. So later when hitting the
director i tried with higer concurrency and there is marginal increase in
the TPS.
I am not sure how much %age of increase in TPS we can expect via Load
balancer.
