Subject [jira] [Commented] (HBASE-10791) Add integration test to demonstrate performance improvement
Date Tue, 08 Apr 2014 08:53:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13962720#comment-13962720
] 

Nicolas Liochon commented on HBASE-10791:
-----------------------------------------

The perfs are terrible when the two replicas are on the same RS. If they are on different
RS it becomes reasonable, but not perfect: I'm seeing a 15%  degradation, with the 2 RS located
on the same machine.

> It would be good to demonstrate that use of region replicas reduces read latency. PerformanceEvaluation
can be used manually for this purpose, but it's not able to use ChaosMonkey. An integration
test can set up the monkey actions and automate execution.
