In SIMULATION AND EVALUATION section, CPU utilization is shown with varying
parameters (such as sigma).
Before putting QoD In production, user would make experiments and adjust
these parameters to achieve desired resource utilization.

Are you going to attach patch onto
HBASE-1734<https://issues.apache.org/jira/browse/HBASE-1734> or
log a new JIRA ?

Cheers
