> PerfEval tool provides a {{--rows=R}} for specifying the number of records to work with
and requires the user provide a value of N, used as the concurrency level. From what I can
tell, every concurrent process will interact with R rows. In order to perform an apples-to-apples
test, the user must re-calculate the value R for every new value of N.
> Instead, I propose accepting a {{--size=S}} for the amount of data to interact with and
let PerfEval divide that amongst the N clients on the user's behalf.
