One thing to note from the github link: echo 1 > /proc/sys/net/ipv4/tcp_low_latency That was deprecated in 2017. The sysctl is still there, but doesn't actually do anything in newer kernels. There are a few other ways to lower latency at the expense of throughput but I will let folks research that themselves.
