How do you define a burst? If it is more than one packet
sent without waiting between them, then isn't the window
size of a TCP connection its burst size?

Of course, a qdisc or something at a lower level may
break up a window's worth of packets. Still, saying
TCP is not bursty at all doesn't seem accurate.

TCP does not send a receive window size at a time because it is also constantly limited by the congestion window. Sending is then regulated by the reception of ACK (one every two packets).

So a (single!) TCP connection is practically never bursty in normal conditions.
