No, the frequency at which the startd policy expression knobs (like
KILL, PREEMPT, START, SUSPEND, etc) are evaluated is controlled by
config knob POLLING_INTERVAL, and defaults 5 seconds.
FWIW, the polling frequency for the job periodic expressions (like
periodic_hold, periodic_remove, etc) is not five minutes per se, but is
controlled by config knobs PERIODIC_EXPR_INTERVAL,
MAX_PERIODIC_EXPR_INTERVAL, and PERIODIC_EXPR_TIMESLICE. Default rate
starts 60 seconds, but this rate could be automatically reduced to
protect schedd performance.
