-------------------------------------------------------
Commit ba56774fa1c16d935f592df482e74bfa1564b5a3 in nifi's branch
refs/heads/master from [~markap14]
[ https://git-wip-us.apache.org/repos/asf?p=nifi.git;h=ba56774 ]
NIFI-4151: Updated UpdateAttribute to only create JAXB Context once; Minor
performance tweaks to standard validators and StatusMerge.prettyPrint; updated
AbstractConfiguredComponent to not create a new ValidationContext each time
that validate is called but only when needed; updated FlowController,
StandardControllerServiceProvider, and StandardProcessGroup so that component
lookups can be performed using a ConcurrentMap at FlowController level instead
of having to perform a depth-first search through all ProcessGroups when
calling findProcessor(), findProcessGroup(), findXYZ()
This closes #1979

> I have a flow with > 1,000 Process Groups and 2500 Processors. A few thousand
> connections and input/output ports as well. When I refresh stats it is taking
> 3-4 seconds to pull back the status. And when I go to the Summary table, it's
> taking about 8 seconds.
