------------------------------------------------
Ok thanks [~anastas].
I did some experiments by changing these hard coded values and found
siginificant changes in GC pause time. But not on the overall PE results. I
need to check my reports.

> According to the new performance results presented in the HBASE-16417 we see
> that the read latency of the 90th percentile of the BASIC policy is too big
> due to the need to traverse through too many segments in the pipeline. In
> this JIRA we correct the bug in the merge sizing calculations and allow
> pipeline size threshold to be a configurable parameter.
