IMHO there could indeed be room for increasing the initial window. If
most data transfers continue to be smaller than 3 MSS, a larger initial
window would not necessarily cause harm, as it is seldomly used. Still,
this would speed up those data transfers that currently suffer from
Slow-Start.

In the past, I have played a little bit with an initial window e. g. of
10 MSS, and that worked surprisingly well. Also, one could combine a
larger initial window with other mechanisms that would reduce the
aggressiveness of the flow startup. Maybe it is indeed time to think
about the Slow-Start once again.
