Benchmark clarification

[dmitrivainbrand]

Hi Priya,
It is unclear how you run the benchmark. I noticed that for best results I need to run each unit-test independently. Otherwise the first tests seem to "steal" memory from later tests. If the benchmark is intended to run as a whole, probably need to find a way to clean the memory between the tests. Otherwise, maybe need to state clearly in the Readme that the tests are supposed to run independently.
Thanks
Dmitri
