TCP Tuning

Suggestions

initrwnd 10 This makes the initial congestion window of 10, as tested by google. Default is 3 1

How do we implement this without just having an ip route command script on startup ?

tcp_fin_timeout 2 Lower our tcp_fin_timeout by 1 second. This matters if the other side does not respond to tcp_fin's. No need to keep this beyond 2 seconds as connections with an RTT > 2 seconds are basically dead anyways.

can use puppet implemented files of sysctl.conf or look in puppet labs and use a module to implement.
