Config Redis Cache with Magento 2
1. Raise somaxconn above [tcp-backlog] value:
sudo nano /etc/rc.local
Add this:
sysctl -w net.core.somaxconn=65535
When you reboot the next time, the new setting will be to allow 65535 connections instead of 128 as before.
2. Make sure to disable Linux kernel feature transparent huge pages, it will affect greatly both memory usage and latency in a negative way. This is accomplished with the following command:
echo never > /sys/kernel/mm/transparent_hugepage/enabled.
then add the command to your /etc/rc.local file.
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
