29 When "scan delay" decreases, the scan rate increases. The scan delay and
30 hence the scan rate of every task is adaptive and depends on historical
31 behaviour. If pages are properly placed then the scan delay increases,
32 otherwise the scan delay decreases. The "scan size" is not adaptive but
33 the higher the "scan size", the higher the scan rate.
