"Lag" in the original poster's case, is actually referred to as
"latency" in the world of computer networking. Latency is defined as
the time it takes to set up and send a message,

Well, it's the overall transmission time from source to destination. The
overhead to set up and send a satellite packet isn't really any worse
than anything else, it just takes a long time to deliever.

Since all data is transported in TCP packets (in the case of Web
traffic), there is continual send AND receive on BOTH sides since TCP
requires acknowledgement of every packet on the part the of the
receiver (remember, TCP is a *reliable* protocol).

Actually, it's acknowledgement of the position in the byte stream.

Granted, the ACK
packets are much smaller than the data packets

There's no such thing as an ACK packet. A TCP packet can have
data as well as the ack for data received.

I wouldn't say there's "no such thing". The people I work with
generally call a packet with the ACK bit set an "ACK". :-). And
if you examine the packets flying in and out during a web surfing
session, they usually don't contain any data.

The latency in the network is going to affect the retransmission
timer on the sending end. Delay is delay. It's not constant, but
it is cumulative.

I'll concede, though, that as long as the acknowledgement timing is
not highly variable, the window will stabilize and you'll get your
nominal throughput *for that particular HTTP request*. Another click
or a redirect and, presto, another delay. It all adds up.

Sorry to flog the dead horse... I'll shut up.
