Increasing the TCP initial congestion window

There are a couple of other things that should be done:
First, the minimum retry time out should be reduced to approximately 1 ms, or whatever the timer accuracy allows. On local area networks a MIN_RTO of 1 second is ridiculous. Second, the syn retry timeout should be reduced from 1 second to 200 ms or so. The only reason to have it so high is if the bottleneck link is a 56 kbps modem or something.
It would be great if there were route attributes that allow these numbers (or something that allows them to be derived) to be further customized on a route specific basis. In particular to increase them on the default route in the case of a unusually slow link, and to decrease them for the route to the local LAN.
