You probably want to bump up the middle value (the default receive 
window size - the values are "min default max"). It needs to be at 
least bandwidth*latency ((512/8)*1.2), if not 2 or 3 times that to 
get good TCP performance.

The fact that you get 60kbps (eventually[1]) over your sat link 
suggests the default is already big enough though.

1. TCP slow start takes a while to ramp up on high-latency links
