I have two changes to ip route & sysctl that disable tcp slow start.
Here’s how I do it
ip route show
Make a note of the line starting with default.
Pick up the IP from the default line and run
sudo ip route change default via $ip_address dev eth0 initcwnd 12
sudo sysctl -w net.ipv4.tcp_slow_start_after_idle=0
How can I create a puppet script out of this? One that can be deployed to many machines of the same type – CentOS 6
Edit: Added bounty to get a working example for
sudo ip route change default via $ip_address dev eth0 initcwnd 12
