I want to point out a minor point. For most implementations, like BSD, the
idle interval for TCP to restart slow start is usually 1 RTO, which is greater
than 1 RTT. So as long as the client can parse the page and generate next
requests in less than half of RTT, the server TCP will not restart slow start.
Actually, if we also count the time the ACK for the last segment from server
to get to the server, the client has even "more" time. So it is not that a
client machine has to rush, but maybe a user has to rush in reading a page to
avoid slow start (-:
