-------------------------------
Which one you want [~bbeaudreault]? We don't seem to have the meter in our
armory (see DynamicMetricsRegistry) to do the percentage that you point to in
the 0.8 abve. We have a Rate as in 0.9 pointer above. What did you fellows do?
I like the idea of percentage occupancy so you can tell if you need to up
Readers/Handlers. Thanks.

> Our ipc Readers are hard coded at 10 regardless since . Running w/ less
> Readers, we go faster..(e.g. 12 Readers has us doing 135k with workloadc and
> 6 readers has us doing 145k).. .but hard to tell what count of Readers are
> needed since no metric.
> This issue changes Readers to be 1/4 the installed CPUs or 8, whichever is
> the minimum, and then adds a new hbase.regionserver.ipc.runningReaders metric
> so you have a chance seeing whats needed.
