I think I figured out State Retention (a piece of it at least <smile>)
When (in nagios.cfg)
    retain_state_information=1
Nagios 'remembers' the host/service state when you restart Nagios.
   If set =0
then Nagios has to perform all the checks before It 'knows' your 
complete system status. MY checks are set to 
    normal_check_interval           20
So It took Nagios 20 minutes to determine everything when I turned it 
off. As nagios.cfg comment says:
   "Since its only a one-time penalty, I think its well worth the 
additional startup delay."
I keep mine on now <grin>.
