  I can't actually answer that question, but if you do
obtain response time and the number of request-response pairs
per second (equivalent to TPS), it's surprising how much
you can discover from just that.
  That data and Little's law allows you to compute the
utilization, the queue length under load, and the increase
in response time due to the queuing.
  Anyone interested in performance on this list?
