Support for RFC3390?
I have an application which can benefit from the TCP window being 4 in lieu of 1 after entering slow start. On BSD, there is a sysctl variable to enable this. Testing results show the benefit (again, in my application.)
I'd like to enable the same on my Linux systems, but searching for rfc3390 doesn't turn anything up.

I'm not certain, but I think you want sysctl variables net.ipv4.tcp_window_scaling and net.ipv4.tcp_wmem.
You can read a description of each with this command:Code:
man 7 tcp

Those are not what I'm looking for. Not only did I read the man page, I read the source code too. I either missed the logic, or don't know what patch I need to apply. RFC3390 lets the initial window size be > 1.
