RFC3390 has increased the initial window from 1 segment to up to 4 segments. The initial window increase of RFC3390 wasn't reflected into the restart window which remained at its original defaults of 4 segments for local and 1 segment for all other connections. Both values are controllable through sysctl net.inet.tcp.local_slowstart_flightsize and net.inet.tcp.slowstart_flightsize. The increase helps TCP's slow start algorithm to open up the congestion window much faster.
