> Performed RU on 1200 node cluster and the progress of 'Core Slaves' restarts is extremely
slow - In 3 hours it restarted only 22 components (screenshot attached). At this rate it will
take weeks for RU to complete.
> It we look into the agent log where RU core-slaves finished, we see that sequential commands
are sent 8 minutes apart - which is very slow. The commands themselves execute in under a
minute.
