A. I want to manually set the Window Clamp for my experiment.I came to
know we can do that in net/ipv4/tcp_output.c::tcp_grow_window. I'm
really confused with the flow. Even i tried in
net/ipv4/tcp_output.c::tcp_select_window, but things are asusual.
B. Can I really improve the throughput by increasing the buffer space ?
Do i have to go for netfileters or altering the existing data structure will do ?
AFAIK you don't set it in the kernel but in the application. Please note 'man 7 tcp' says clamp isn't portable. For a code example see this. And increasing buffer space is not the only thing you must take into account when trying to maximize throughput, see the TCP Tuning Guide and the Ipsysctl tutorial 1.0.4.
