I noticed the following warning in my rebuild log:

` # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.`

I was doing some reading and [found some suggestions to raise this value](https://www.techandme.se/performance-tips-for-redis-cache-server/). Should I? Will this help performance of our platform?
