> In StatisticsMonitor and StatMonitorHandler List is used to store monitors,
> listeners and statisticIds.
> We should be using ConcurrentHashSet for performance Reason.
> In my local testing When I replace the List to
> com.gemstone.gemfire.internal.concurrent.
> ConcurrentHashSet
> I see significant improvement in creating large number of region creation.
> ( from ~7hrs to ~26 minutes)
> More details about the same is on dev list.
