+MLRsearch discovers all the rates in a single pass, reducing required time
+duration compared to separate `binary search`_es for each rate. Overall
search time is reduced even further by relying on shorter trial
durations of intermediate steps, with only the final measurements
conducted at the specified final trial duration. This results in the
shorter overall execution time when compared to standard NDR/PDR binary
search, while guaranteeing similar results.
-If needed, next version of MLRsearch can be easily adopted
-to discover more throughput rates with different pre-defined PLRs.

.. Note:: All throughput rates are *always* bi-directional
aggregates of two equal (symmetric) uni-directional packet rates
received and reported by an external traffic generator.
