The following hosts have Transparent Huge P         


        

Answer 1

Did you try this command:

sudo su
echo never > /sys/kernel/mm/transparent_hugepage/enabled

?

Alternatively, you may install hugepages

sudo su
apt-get install hugepages
hugeadm --thp-never

As mentioned by @Anthony, the effect would not persist after a reboot. Use your distribution-specific method to do that every time after reboot.
