Description: We need the following set manually:

echo 360448 > /proc/sys/vm/min_free_kbytes
echo 1 > /proc/sys/vm/zone_reclaim_mode
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

and added to /etc/sysctl.conf.

echo "vm.min_free_kbytes = 360448" >> /etc/sysctl.conf
echo "vm.zone_reclaim_mode = 1" >> /etc/sysctl.conf

and figure out why rc.local is not setting hugepage defrag even though that line is already there.]]>
