question on TCP slow start# Programming - 葵花宝典

I understand it as follows (please point out my errors, if it's wrong):
TCP starts sending congestion_window_size=SLOW_START_VALUE packets, then
wait for acks, with each ack, congestion window is increased by 1,
essetially doubling it with every sending.
but I did a tcpdump, and send out a 8000byte msg, which is sent out in 6
1xxx-byte packets, then all the 6 packets are sent out immediately, without
waiting for the ack. so slow start is not working here ???
Thanks
