Seems to me that sshd should, but does not, set TCP_NODELAY on the port
used for X11 forwarding. I am not sure about other forwarded ports;
sshd seems to set TCP_NODELAY and also IPTOS_LOWDELAY on the "command"
connection only.

Quoting from
http://www.openssh.com/txt/release-3.1
   - TCP_NODELAY set on X11 and TCP forwarding endpoints

Is this a bug that could be fixed?

Thanks, Paul

What it does not set is IPTOS_LOWDELAY ... but maybe that is not
useful anyway.

Cheers, Paul
