Hi,

I want to modify my advertised window size so that I get better interactive 
performance on my modem whilst downloading for example.

I've tried using the route options "-lockrest -sendpipe 4096 -recvpipe 4096 
-mtu 576" for example. Then I do a do "route <host>" and all the options are 
there like they should be.

Then I start a session with that host, but when you look at tcpdump's output, 
it's still using the ones in the sysctl, net.inet.tcp.recvspace and 
net.inet.tcp.sendspace. It feels like it too, it saturates the whole 
connection.

Any ideas how I can make it use different window sizes for different routes?
