Which path checker are you using? 
If it's TUR, could you try to simply change the sync wait time?

static void tur_timeout(struct timespec *tsp)
{
        get_monotonic_time(tsp);
        tsp->tv_nsec += 1000 * 1000; /* 1 millisecond */
        normalize_timespec(tsp);
}

Change the 1 millisecond above to e.g. one microsecond. That should
speed up the checker significantly. You will get a higher rate of
"pending" path states, but that shouldn't matter much.
