#
# The low- and high-water marks for cache object replacement.
# Replacement begins when the swap (disk) usage is above the
# low-water mark and attempts to maintain utilization near the
# low-water mark. As swap utilization gets close to high-water
# mark object eviction becomes more aggressive. If utilization is
# close to the low-water mark less replacement is done each time.
#
# Defaults are 90% and 95%. If you have a large cache, 5% could be
# hundreds of MB. If this is the case you may wish to set these
# numbers closer together.
