TCP slow start
n  Initial Congestion Window (IW)=10
⁃  only 10 packets can be sent in first RTT
⁃  used to be IW=3

Why 1.5x?
During slow start, a TCP increments cwnd by at most SMSS bytes
for each ACK received that cumulatively acknowledges new data.
(snip)
The delayed ACK algorithm specified in [RFC1122] SHOULD be
used by a TCP receiver. When using delayed ACKs, a TCP
receiver MUST NOT excessively delay acknowledgments.
Specifically, an ACK SHOULD be generated for at least every
second full-sized segment, and MUST be generated within 500 ms
of the arrival of the first unacknowledged packet.
TCP Congestion Control (RFC 5681)

Flow of the ideal HTTP
n  fastest within the limits of TCP/IP
n  receive a request 0-RTT, and:
⁃  first send CSS/JS*
⁃  then send the HTML
⁃  then send the images*
*: but only the ones not cached by the browser
