Redis-Queue Log Warnings

Self hosted ERPNext on Digital Ocean VPS. Seeing the following warnings in the redis-queue.log file along with suggestions… Is it safe to follow those recommendations? or ok to ignore? Appreciate any suggestions.

2257:M 26 Apr 19:15:44.328 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

2257:M 26 Apr 19:15:44.328 # Server started, Redis version 3.0.6

2257:M 26 Apr 19:15:44.328 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.confl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

2257:M 26 Apr 19:15:44.328 # 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.
