This is rather a thing we would change in CVS HEAD. If you really want
To change it right now (e.g. for testing), change tcp_in.c line 567
in CVS HEAD (I think line 538 in v1.2.0; tcp_process()
switch(pcb->state)
case SYN_RCVD) from 'pcb->cwnd = pcb->mss;' to 'pcb->cwnd = 2 *
pcb->mss;'

But I'd suggest to upgrade to a newer version (CVS HEAD or the
'upcoming'
1.3.0)...
