The RTTs vary massively because the router is forwarding from websites on the LAN to visitors worldwide. Is that what you meant ?
And your TCP speed when doing testing is always 300-600 kilobyte/s regardless of RTT between the boxes with which you're testing? Without TCP window scaling turned on on the boxes doing TCP with each others, you're always limited to 1/RTT*64k bytes/s of transfer speed. Changing window scaling on the linux router will of course not change the behaviour of the traffic going thru it, only TCP sessions that itself does. -- Mikael Abrahamsson email: swmike@swm.pp.se
