Subject [jira] [Created] (HBASE-9780) Total row num to write in PerformanceEvaluation vary on thread number
Date Wed, 16 Oct 2013 07:59:43 GMT
Liu Shaohui created HBASE-9780:
----------------------------------

             Summary: Total row num to write in PerformanceEvaluation vary on thread number
                 Key: HBASE-9780
                 URL: https://issues.apache.org/jira/browse/HBASE-9780
             Project: HBase
          Issue Type: Improvement
            Reporter: Liu Shaohui
            Priority: Minor


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?
