------------------------------
+1 Commit and I'll try it. Let me explain over in the modulo issue how it does
similar but I like your take better (After trying this, may back out the modulo
arg)

> 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.
