# WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. 
# This will create latency and memory usage issues with Redis. 
# To fix this issue run the command
# 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, 
# and add it to your /etc/rc.local in order to retain the setting after a reboot.
# Redis must be restarted after THP is disabled.
