With the default splaytime of 1 minute, every host will execute its policy at some time during that minute (fixed delay of 1-60 seconds based on hostname), fairly well spread out based on my testing. So for every 100 systems, 1 to 2 systems would execute policy every second at the same 5 minute intervals (i.e. the schedule variable). When I get my initial 500 systems going, that will be 5-10 retrievals per second, unless I increase splaytime, in which case it takes longer for each system to complete each cf-agent invocation.
Plus, by randomly distributing certain work throughout the day, I'm less concerned about systems being down and not doing something that was specified at a certain time.

If each agent is started with the executor it will delay using splaytime. Thus the db host will not get all connections at once.
