Jean-Marc Spaggiari commented on HBASE-9780:
--------------------------------------------
Hi Liu,
I figured that some time ago, but changing it will break the behavior
compatibility between new versions and older versions. So I think we should
"simply" document that and keep it like that.

>
> Total row num to write in PerformanceEvaluation vary on thread number
> {code}
> // Set total number of rows to write.
> this.R = this.R * N;
> {code}
> Different row num may result in different random read perf. More threads,
> More rows, may less block cache hit raito.
> Should we make the total row num be immutable for different thread numer?
