Changing initcwnd
Adjusting the value of the initcwnd setting on Linux is simple. Assuming we want to set it to 10:
Step 1: check route settings.
sajal@sajal-desktop:~$ ip route show 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.100 metric 1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 192.168.1.1 dev eth0 proto static sajal@sajal-desktop:~$
Make a note of the line starting with default.
Step 2: Change the default settings.
Paste the current settings for default and add initcwnd 10 to it.
sajal@sajal-desktop:~$ sudo ip route change default via 192.168.1.1 dev eth0 proto static initcwnd 10
Step 3: Verify
sajal@sajal-desktop:~$ ip route show 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.100 metric 1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 192.168.1.1 dev eth0 proto static initcwnd 10 sajal@sajal-desktop:~$
