Enis Soztutar commented on HBASE-10791:
---------------------------------------
One thing to consider is to look at how many more RPC's are caused by the
backup requests. If you are running with the default 10ms secondary rpc delay,
and the average latency is around that, it would increase the request count a
lot.
I can also spend some time inspecting what is going on.
> Add integration test to demonstrate performance improvement

> 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.
