             Summary: Ambari Server hangs generating tasks for install+start when adding 600

I deployed one of the PERF clusters using code from trunk with 600 agents.
Upon trying to add another 600 agents, I was able to register the hosts manually through the
UI, but the server would get stuck when generating the install+start tasks.
I waited for over 30 mins and it was stuck.
Refreshing the page caused it go go back to that same step in the wizard, so I had to exit
the dialog and start those services on my own.
Because this was the PERF stack, there were no actual bits to install. This points to a performance
problem on the server.
