Subject [jira] [Created] (HBASE-12335) IntegrationTestRegionReplicaPerf is flakey

------------------------------------

             Summary: IntegrationTestRegionReplicaPerf is flakey
                 Key: HBASE-12335
                 URL: https://issues.apache.org/jira/browse/HBASE-12335
             Project: HBase
          Issue Type: Test
          Components: test
            Reporter: Nick Dimiduk


I find that this test often fails; the assertion that running with read replicas should complete
faster than without is usually false. I need to investigate further as to why this is the
case and how we should tune it.

In the mean time, I'd like to change the test to assert instead on the average of the stdev
across all the test runs in each category. Meaning, enabling this feature should reduce the
overall latency variance experienced by the client.
