TCP Thin-Stream Modifications

I have read the below article and I am going to give it a go in my laptop

First, check the status of tcp thin:

# sysctl net.ipv4.tcp_thin_linear_timeouts
net.ipv4.tcp_thin_linear_timeouts = 0

I have realised that I dont have “/proc/sys/net/ipv4/tcp_thin_dupack” as the article mentions…

Ok, let update the value and be sure is still active after reboot.

Enable the value:

# echo "1" > /proc/sys/net/ipv4/tcp_thin_linear_timeouts
# sysctl net.ipv4.tcp_thin_linear_timeouts
net.ipv4.tcp_thin_linear_timeouts = 1

Make it permanent, edit /etc/sysctl.conf like this

# Based on https://www.simula.no/file/lj-219-jul-2012pdf/download
# enabling tcp thin-steam modifications for reducing latency in interactive apps
net.ipv4.tcp_thin_linear_timeouts = 1

Now it is time to test and see if you see any improvement or degradation!
